为解决留矿采矿法开采破碎、不稳固矿体所带来的矿石贫化损失问题,依据现代连续采矿思想,结合矿山生产实际情况,提出无间柱连续推进分段空场崩落采矿法。通过不留间柱连续推进、随时开采随时出矿、利用顶板围岩自然崩落处理采空区等技术,解决了使用传统方法开采此类矿体所带来的问题,矿块生产能力达到150 t/a,贫化、损失指标分别从60%,36%下降至12%,11.5%,效益明显。
In order to solve the problem of ore depletion loss caused by the mining of broken and unstable ore by the residual ore mining method, according to the modern continuous mining thought and the actual production of the mines, the mining method of continuous plowed-free sub-level caving is put forward. Through the continuous propulsion without leaving the column, mining at any time at any time, the use of roof caving natural caves processing technology to solve the problems caused by the use of traditional methods of mining such ore body, nugget production capacity of 150 t / a, depletion, loss indicators decreased from 60%, 36% to 12%, 11.5%, the obvious benefits.
