The operator of each mine has the right to adopt special safety rules for the safety and operation of his mine, covering the work pertaining to the mine inside and outside of such mine. Such special safety rules shall not be in conflict with the provisions of the Act and, when established, shall be posted at some conspicuous place about the mine where the rules may be seen by all miners at such mine or in lieu thereof shall be furnished by the operator as a printed copy to each of the miners.
