煤焦共采采掘工艺探讨

Discussion on the excavation craft of coal mining together with natural coke

针对矿井剩余煤炭储量接近枯竭的实际情况,进行了天然焦开采工艺研究。分析了矿井天然焦的分布储存情况,总结矿井天然焦回采存在的主要问题;就天然焦的物理和化学性质,提出了采掘现场技术要点及施工措施,重点研究了采、掘共有的丢炮难题。实践证明,经济效益显著,安全效果良好。

In view of the mine actual situation of coal resource approaching exhausted, natural coke excavation craft was studied. The distribution of natural coke was analysed, and the main problems of natural coke stoping were summarized. In view of the physical and chemical properties of natural coke, the technical main points and construction measures were put forward, and the unexploded hole was studied emphatically. The production practice proved that good economic benefit and safety effect were obtained
