篦子沟矿自投产以来,随着生产建设的不断发展,采矿方法也相应地得到改进和完善。本文介绍我矿使用挤压爆破有底柱分段崩落采矿法的采准结构和回采方案。我矿属于岩浆期后高中温热液细脉浸染似层状铜矿床。主矿体(2号矿体)占全区总储量的94.5%,走向长300米,倾斜长500米,平均厚度29.5米,倾角20～40°;西北
Since Gazi ditch mine put into production, with the continuous development of production and construction, mining methods have been improved and improved accordingly. This paper introduces the mining quarrying scheme and mining scheme of the sub-caving sub-caving mining method using extrusion blasting. My mine belongs to stratigraphic copper deposit after high-temperature hydrothermal vein dissemination in the magma period. The main ore body (No. 2 ore body) accounts for 94.5% of the total reserves in the region, with a strike length of 300 meters, an inclined length of 500 meters, an average thickness of 29.5 meters and a dip angle of 20 to 40 degrees.
