采用长锚索预控顶和短锚杆护顶的联合控顶技术及连续分条尾砂充填采矿法开采顶板不稳固的缓倾斜薄矿体是国内首创。实践证明它具有采场生产能力大、工效高、贫化率和损失率低、安全条件好、经济效益高等优点。本文以湘西金矿为例介绍其回采工艺、控顶技术和采场安全监测、光弹、相似模拟试验及边界元计算的结果。 The combination of controlled roof technology with long anchor pre-control roof and short anchor roof and the continuous mining of sub-tailing tailings mining method are not the first of its kind in China. Practice has proved that it has the advantages of large production capacity, high work efficiency, low depletion rate and loss rate, good safety conditions and high economic benefits. This paper takes the Xiangxi Gold Mine as an example to introduce the results of its mining technology, roof control technology, stope safety monitoring, photoelasticity, similar simulation and boundary element calculation.
