CHAPTER XII

PRECAUTIONS AGAINST COAL DUST

REGULATION 44. GENERAL PROVISIONS

1.

(1) National laws or regulations shall define dangerous

coal dusts as to their explosive qualities in order to determine how

dusty mines are to be classified, and the precautions to be taken

in each case shall depend upon the classification.

(2) This classification shall not be undertaken by the competent

authority without prior consultation with employers' and workers'

representatives.

REGULATION 45. PREVENTION AND SUPPRESSION

OF

DANGEROUS COAL DUST

1.

(1) Where necessary, water shall be conveyed to all working

faces and used for allaying dust, or other effective measures shall

be taken for this purpose at working faces.

(2) Tubs shall be so constructed and maintained as to prevent

coal dust escaping through their sides, ends or floor.

(3) When coal produces fine and dangerous dust, the tubs

loaded with coal shall be amply wetted with water, or water with

a wetting agent, at the latest when they enter the main haulage

roads.

2.

In roads that are regularly used for haulage or travel,

and in main airways, any considerable quantities of dangerous

dust shall be periodically collected and removed.

3.

The manager shall make all such arrangements as are

practicable for the reduction of dust on conveyor roads, and

at conveyor junctions and loading points.

4.

(1) Precautions shall be taken at the surface to prevent

coal dust from entering the downcast shaft in considerable quan-

tities,

and the shafts and their approaches shall be cleared of any

accumulation periodically.

(2) In the case of a mine newly opened, no plant for the

screening or sorting of coal should be situated within a distance

of 80 m (260 ft.), or such other distance as may be specified in
