摘要
针对大南湖二号露天煤矿开采煤层多、煤层累计厚度大、极易自燃的特性,结合露天开采理论,提出优化开采程序来防止非工作帮台阶煤层自燃事件,开采程序优化对露天煤矿经济效益有积极的影响,在实际生产应用中对防止煤层自燃效果明显,有利于边坡稳定,对于我国新疆煤炭基地易自燃煤层开采具有一定的借鉴意义。
In view of the characteristics of multiple seam, large accumulative thickness and easy spontaneous combustion in the Dananhu No.2 Open-pit Mine, we put forward the optimization of mining procedure to prevent coal seam spontaneous combustion under the non-working slope. The mining procedure optimization has positive influences on economic benefit of the open-pit mine, and has obvious effect on prevention coal seam spontaneous combustion in production applications and also beneficial to slope stability, which has certain reference significance for the exploitation of the spontaneous combustion coal seam in Xinjiang coal base of China.
