摘要
煤矿自燃矸石山是矿区一大污染源。本文研究了粉煤灰、电石渣这两种工业废弃物作为治理自燃矸石山的灭火材料的可能性。实验室试验表明，在一定的配比下它们具有良好的阻燃性。现场工程获得了成功，不仅取得了良好的环境效益，也取得了良好的经济效益。
Burning waste heap is one of the major air pollution sources in. coalmine areas.This paper studied the possiblity of extinguishing the spontaneous.com-bustion of waste heap with fly ash and the sludge of calcium carbide. The laboratorytests showed that they are good for extinguishing spontaneous combustion of wasteheap when they are in proper proportion. The field test was successful and not onlyimproved the environment of coal mine area. but also got good economical benefit.
