摘要
系统地阐述了开采缓倾斜极薄矿体所面临的技术现状,结合新疆拜城县滴水铜矿的实际情况,创造性地采用了"长壁分条、堑沟削壁、移架放顶"全面采矿法,从凿岩工具、爆破方法及采用沿空留巷等技术方面进行创新,成功地解决该矿山缓倾斜薄矿体面临的技术难题,为矿山带来了良好的经济效益,同时,该采矿方法的成功运用为其他类似矿山提供了参考。
The technical stains of mining inclined extra-thin ore body was systematically described.Combined with the actual conditions of Dishui Copper Mine in Baicheng County,Xinjiang,the’longwall strip,trench cliff,frame shift caving’comprehensive method was adopted creatively,and the innovations of rock drilling tools,blasting method and the gob-side entry retaining were made.It successfully resolved the problems of gently inclined extra-thin ore body mining technology and got good economic benefit.At the same lime,the success of the mining method provided a reference for other similar mines.
