Study on the Effects of "three violations" data in the design of coal mine safety signs

摘要

The "three violations" data is an important basis for the design of coal mine safety signs. This paper studies one of the design basis, which is, “three violations”, for the reason and application process, get the following conclusion: according to mine "three violations" data in coal mining face, for example, the coal mining working face is divided into six parts, namely mobile substation jobs unit, pumping operations unit, scraper conveyor operations unit, belt operation unit, coal mining operations unit and ends, advance support operations unit. In coal mining operations unit, for example, the coal mining operations unit staff is divided into eight types, namely, drilling workers, blasting workers, caving workers, haul workers, frame shift workers, shearers drivers, clean coal workers. The mining operations units and types of violations correspondence. Based on the above design eight mine safety signs, are prohibited underground sleep, prohibited get in ban car until car complete stop, prohibit sit explosives boxes, must clear float coal, must wear masks, must hold relevant certificates and must open spray, must use U steel clamp.
