复杂地质条件下空巷间煤柱回采技术

摘要

four with the Datong Coal Industry Group Company Sitai Coal Mine 14#81204 working face of the application layer of technology between coal pillar recovery abandoned roadway new technology to reduce the impact of complex geological conditions and the same abandoned roadway work for mining, improved recovery of coal resources, extended face service time, increase the safety factor of the staff working environment, to ease the tension connection time work. Through the analysis on the same layer of abandoned roadway technology under complicated geological conditions, in order to face similar production to provide some reference.%同煤集团四台矿14#层81204工作面对新工艺回收空巷间煤柱技术的应用，降低了复杂地质条件和同层空巷对回采工作的影响，提高了煤炭资源的回收率，延长了工作面的服务时间，增加了员工工作环境的安全系数，缓解了工作衔接时间紧张的局面。通过对复杂地质条件下的同层空巷技术进行分析，为类似工作面的生产提供一些借鉴。
