摘要
新城金矿ⅴ#矿体属于典型厚大破碎矿体。结合矿山实际情况,采用预控顶上向中深孔分段充填法开采矿体。通过预控顶支护有效地保证了采场顶板和上盘围岩稳定性,并采用上向扇形中深孔回采矿石,实现了矿体安全连续高效开采。
The ore body type of the ⅴ# ore body in Xincheng gold mine is the typical thick broken ore body.Based on the actual situation of the mine,decide to mine the ore body with the pre-roof-controlled upward mediumlength hole sublevel mining with backfill.By the pre-roof-controlling,to ensure the roof and upper wall safety,moreover with the upward medium-length hole mining,mining the ore body safety and efficacy came true.
