| 中文摘要: |
| 在地表不允许崩落的情况下,松散破碎矿体回采,不能采用崩落法和空场法,而胶结充填成本又太高.文章以大宝山矿2#主井②矿体为例提出采用胶结充填回采矿柱、干式充填回采矿房,连续采矿、分步实施的采矿方法,就采矿工艺、充填方法、安全保障措施进行探讨,与传统方法相比,在安全、效率、成本、回采率、最低可采品位等多项安全、技术经济指标上取得了成效,具有一定的推广应用价值. |
| 英文摘要: |
| Under the situation that the earth's surface does not allow collapsing,relax broken ore body can not adopt a caving mining and leave the cost modeling after,but the cost of cementing filling empty is very high.The article takes Dabao mountain ore 2# main shafts ore bodies as example and suggests the methods of cement and dry style of backstoping filling,continuous but step by step mining.Its mining handicraft,filling method,insurance measure are discussed and compared with traditional method,which have certain application and dissemination value on technology economic targets such as safety,efficiency,cost,rate of recovery,minimum grade. |
