摘要
滇滩水城萤石矿的生产规模为4万t/a,是座小型矿山,开拓方式为平硐开拓。矿岩破碎、稳固性差,开采过程中常发生冒顶、片帮、塌方等安全事故,矿山开采采用分层崩落采矿法。通过试验开采,摸清了该采矿方法在滇滩水城萤石矿V1矿体回采中的结构参数、矿体布置、适用条件等方面的各项工艺参数,证明分层崩落法完全适用于滇滩水城萤石矿V1矿体的回采。
Diantan Shuicheng fluorite Mine with the capacity of 40 000 t/a is a small mine, and it is opened up by tunnels. Due to the fractured rocks and poor stability, some security accidents such as roof falling, caving and landslide al- ways appear in the mining process. The mine is exploited by the slicing and caving stoping method. Through the tests, vari- ous technical parameters by this stoping method during exploitation of V1 ore body in Diantan Shuicheng fluorite ore are found out, including structural parameters, ore-body layout and applicable conditions etc.. Therefore, the slicing and caving stoping method fully suits for the recovery of Diantan Shuicheng fluorite ore V 1 ore-body.
