同忻煤矿开采技术条件与采掘工艺研究

Study on Mining Technology Conditions and Mining Technology of Tongxin Coal Mine

针对同忻矿井下煤炭采掘效率低下、经济性差的情况,在对井下开采技术条件进行充分分析的基础上,提出了一种新的采掘工艺技术,采用了全新自移式临时支护方案,有效地提升了井下巷道支护作业效率和安全性,能够将采掘效率提升14.1%以上,采掘安全性得到极大提升。

In view of the low efficiency and poor economy of underground coal mining in Tongxin Mine,a new mining technology is proposed based on the full analysis of underground mining technical conditions.The new blasting process and self moving temporary support scheme are adopted,which can improve the mining efficiency by more than 14.1%and greatly improve the mining safety.
