reasonable safety conditions and practices in the mines and the wide variety of types, conditions and methods of mines and mining to which the code must be applicable."

The Administrator made no claim of infallibility for this Federal Mine Safety Code and further stated:

"Undoubtedly, as experience is acquired in the administration of the code, there will be revealed desirable additions, deletions and modifications."

Certainly, the promulgation of a safety code, based upon the experience and investigations of the Bureau of Mines, should be available to the industry and to the State departments of mines, as a standard of perfection, to be considered with such modifications as may be necessary and desirable from actual experience to suit the widely varying conditions in different localities. If necessary, or desirable, revisions in State mining laws should be made to cover, and the enforcement of such laws left in the hands of competent mining men from such departments, experienced in such conditions.

The division of safety and inspection of the department of Industrial Relations of the State of Alabama has an adequate staff of mine inspectors, who are competent mining men, experienced in mining conditions peculiar to that area and who regularly and thoroughly inspect the mines of the State. They have ample authority, under the State laws, to order the suspension of operations of any coal mine or pit or part thereof, where there is an imminent hazard to the workmen. The union mine committee at each mine also has like authority. There is no necessity for further division of this responsibility.

In April 1947, the director of industrial relations of the State of Alabama appointed a committee, composed of an equal number of representatives from the coal operators and coal miners, to review the existing mine safety laws and to make recommendations for revision and strengthening such laws. This committee worked diligently and harmoniously to that end, having the advice of practical and technical mining men with many years of experience in the mining conditions peculiar to that field. In the revision of these laws, the provisions of the Federal Safety Code were given most careful consideration and adopted verbatim, where possible.

Unfortunately, the proposed revision of the mining law, although having the support of both the operators and miners, got caught behind a political log-jam last year and was not passed, but I am happy to state that the Alabama coal mine safety law of 1949-the same bill-passed the Alabama Senate on May 19, and is now before the Alabama House and, as it is an agreed bill, should be enacted into law within the next few days.

This law, gentlemen, we believe, is an excellent coal mine safety law, more rigid in some of its provisions than the Federal Mine Safety Code and it is written to more fully cover the mining conditions peculiar to the district and resulting from the continued improvements in mining methods and equipment. It has the support of the State enforcement agency, the operators and the miners. We feel that it is through such cooperative action as has been demonstrated in this instance, that the cause of safety in coal mining can best be advanced. Again, we urge you to leave the enforcement of mining laws in the hands of capable State agencies, with their personnel experienced in local mining conditions and avoid the unnecessary duplications of effort, confusion as to authority and responsibility, unnecessary expense to the taxpayer, and the coal industry; and let us have the benefit of the services of the Bureau of Mines as the technical, experimental, educational and advisory agency which has rendered much valuable service as such, to the industry and the public.

Mr. KELLEY. The hearing is adjourned.

(Whereupon, at 6:55 p. m., the subcommittee adjourned subject to the call of the chair.)

FEDERAL MINE HEALTH AND SAFETY INSPECTION

AMENDMENTS OF 1949

FRIDAY, JULY 8, 1949

HOUSE OF REPRESENTATIVES,

SPECIAL SUBCOMMITTEE OF THE
COMMITTEE ON EDUCATION AND LABOR,

Washington, D. C.

The committee met at 10 a. m., Hon. Augustine B. Kelley (chairman) presiding.

Mr. KELLEY. The committee will please be in order.

It has been charged at some hearings recently that the John M. Hirst Coal Co. of Ohio has paid no attention to the Federal mine inspector's report when that report requested certain changes to be made because the mine was in a dangerous condition, and for that reason the committee has asked the company officials, the Federal inspectors, and the State inspector of Ohio to appear this morning to testify.

The first witness will be Mr. M. J. Mechling.

TESTIMONY OF M. J. MECHLING, UNITED STATES BUREAU OF MINES, ST. CLAIRSVILLE, OHIO, ACCOMPANIED BY W. J. SYMONS AND R. J. KIRK, FEDERAL MINE INSPECTORS, UNITED STATES BUREAU OF MINES, ST. CLAIRSVILLE, OHIO

Mr. MECHLING. My name is Monroe J. Mechling. I am the engineer in charge, Bureau of Mines, St. Clairsville, Ohio.

Mr. KELLEY. It has been charged that you could get no compliance from the company, or the State mine officials, in regard to the dangerous conditions existing in the John Hirst Co. mine. We would like to have you tell us what you have found as a Federal inspector. Mr. MECHLING. I, myself, did not make the inspection.

Mr. KELLEY. Were you in the mine?

Mr. MECHLING. No, sir; but I did contact the other inspectors as they made their inspections.

Mr. KELLEY. Are the inspectors here?

Mr. MECHLING. We have two inspectors here who were in the mine. Mr. KELLEY. The Bureau of Mines reported that there were some mines that did comply with the recommendations of the Federal mine inspectors. We will now proceed to ask questions of the Federal mine inspectors who inspected these mines.

How often?

Mr. SYMONS. The mine was inspected June 20 to 24 last, and before that, March 21 to March 23.

Mr. KELLEY. Tell us what the conditions were?

Mr. SYMONS. The mine was in bad physical condition.

Mr. KELLEY. Tell us just how.

Mr. SYMONS. Badly neglected?

Mr. KELLEY. Do you have your report?

Mr. SYMONS. This is my report.

Mr. KELLEY. It will be made a part of the record at this point. (Previous reports on the Sterling mine appear on p. 247. The report referred to is as follows:)

COAL-MINE INSPECTION REPORT, STERLING MINE, JOHN M. HIRST Co., NEAR SALINEVILLE, CARROLL COUNTY, OHIO, JUNE 20-24, 1949

(By W. J. Symons, R. J. Kirk, coal-mine inspectors)

INTRODUCTION

This report is based on an inspection made in accordance with the Coal-Mine Inspection and Investigation Act of 1941, Public Law 49, Seventy-seventh Congress, H. R. 2082.

The purpose of this report is to call to the attention of all concerned violations of the Federal Mine Safety Code observed during this inspection and to recommend means of correcting hazards.

Violations of the Federal Mine Safety Code and recommendations for their correction repeated from the previous report are indicated by asterisks.

GENERAL INFORMATION

The Sterling mine, located 3 miles west of Salineville, Columbiana County, Ohio, on Route 39, is opened by two drifts and one shaft in the Mahoning or No. 7-A coal bed, which averages 36 inches in thickness in the present workings. The employment was 149 men, of whom 134 worked underground on 1 shift daily, 5 days a week. The average daily production was 600 tons of coal, loaded by hand. The management estimated the life of the mine to be 9 years.

The mine was developed by a room-and-pillar method. Entries were driven in sets of three, and room entries were driven at intervals of 600 feet. Crosscuts were 60 feet apart.

A systematic method of timbering had been adopted, but safety posts were not set as needed at the working faces. In some places permanent posts were not set within 12 feet of the face.

Coal and rock were blasted on shift with pellet black powder, fired with sulfur squibs. Dynamite, fired with electric detonators, was sometimes used for blasting rock.

Ventilation was induced by a centrifugal fan operated blowing. The fan was installed on the surface 8 feet from the shaft in an incombustible building provided with a fireproof air duct. The ventilation was inadequate in the face regions throughout the mine. Preshift and on-shift examinations for methane were not made. The mine was examined weekly for methane and other hazards. Stoppings along the main entries were constructed of tile and concrete blocks. In 15 east and 12 west single unattended doors were used. In some places line brattice was not used in the face regions where necessary.

The mine was rated nongassy by the Ohio Division of Mines. The analyses of air samples collected during this inspection are shown in table 1. Tests were made with a permissible flame safety lamp in all accessible places during this inspection, but methane was not detected.

Excessive accumulations of coal dust were present along the haulage roads and on the roof, ribs, and timbers. The mine was generally dry, but it had never been rock-dusted. Excessive dust was thrown into suspension during cutting operations but provision was not made to allay dust at its source.

Coal was transported in mine cars by trolley and battery locomotives. Shelter holes were provided, but they were not kept free of obstructions. Clearance was inadequate at several places in recently developed entries, and the clearance space along the haulage roads was obstructed at many places. Men were transported in the regular mine cars. The trolley wire was not guarded at man-trip waiting stations where contact hazards existed.

Electric power, 220 volts alternating current and 275 volts direct current, was used on the surface and underground. Some of the electric power wires were nailed on posts. Cut-out switches were provided at the beginning of branch lines in the active working sections, but they were not provided in the trolley wire from the surface to the working sections, a distance of more than 3 miles. The electric face equipment was of nonpermissible type, but it was maintained in good operating condition. Trailing cables, except those on the electric coal drills, were protected against excessive overload. One substation was on the surface and two were underground.

Underground fire-fighting equipment was inadequate for the size of the mine. Active workings were not approaching abandoned areas.

Escapeways were obstructed by water and falls.

Carbide lamps were used by most of the men for portable illumination underground.

Smoking was practiced throughout the mine.
