12. The minimum width of the working face of the platform step must meet the needs of the personnel working in the mining, loading and transporting machinery and equipment, and should generally be greater than 40m. When the upper and lower steps are simultaneously mined, the upper step must maintain a certain advanced distance.
13. There should be warning signs on the lower part of the waste stone yard. It is strictly forbidden for people to walk or stay.
