Section 220.10  Introduction

and Definitions

a)         Adoption of Regulations-Scope and Authority.

This Part sets forth mandatory safety standards for

bituminous, anthracite and lignite surface coal mines, including open pit and

auger mines, preparation facilities and all other surface work areas of

underground and surface coal mines.  In adopting this part, the Mining Board

implements The Coal Mining Act [225 ILCS 705/2.12 and 38.2].  None of these

rules provide for any protection at a level which is below that established in

the federal standards for surface installation health and safety.

unconfined. A number 8 test blasting cap is one containing 2 grams of a mixture

of 80 percent mercury fulminate and 20 percent potassium chlorate, or a

blasting cap of equivalent strength. An equivalent strength cap comprises

0.40-0.45 grams of PETN base charge pressed in an aluminum shell with bottom

thickness not to exceed 0.03 of an inch, to a specific gravity of not less than

1.4 g/cc., and primed with standard weights of primer depending on the

manufacturer
