摘要
根据侯庄矿床-160m水平以上矿体赋存条件及地表不允许塌陷的状况,提出了一步房、二步房上向分层胶结充填采矿法,一步房胶固粉尾砂胶结充填,二步房尾砂充填。胶结充填采矿法安全性好、回采率高,为矿山技术进步、提高经济效益起到了积极作用。
According to occurrence condition of ore body of Houzhuang ore deposit at - 160m level above and the surface do not allow caves in, first step of room, second step of room upwards lamination stoping-cemented fill method is brought up. The first step of room cemented fills with cementitious material and tails, second step of room fills with tails. The security of the stoping-cemented fill method is good and the rate of extraction is high. It has made the contribution for mine in technical progress and improving economic benefits.
