随着煤炭开采技术的不断提高,煤炭回采、残煤利用对于充分利用煤炭资源、提升煤矿效益日显突出作用。本文基于某煤矿工作层面的回采实践,总结出了回采炮采放顶煤工作技术,并从分别从采面优化设计、掘进、回采等不同角度,探讨回采残煤的实际工程实践。
With the continuous improvement of coal mining technology, coal recovery and residual coal utilization play a prominent role in making full use of coal resources and improving coal mine efficiency. Based on the mining practice of a certain coal mine, this paper summarizes the technology of blasting mining top coal caving, and explores the practical engineering practice of residual coal mining from the aspects of optimal design, excavation and recovery of mining face.
