综放工作面过老巷实践应用研究

Research on the Practice and Application of Fully Mechanized Caving Face Passing Through Old Roadway

为了保障回坡底煤矿11-103综放工作面安全通过其回采范围内的老巷,在分析切巷通过老巷时的层位关系的基础上,提出了过老巷的2套基本方案并进行了方案的确定,提出过老巷的安全技术措施。实践应用效果表明:该技术方案成功地保障了11-103综放工作面安全通过老巷,实现了工作面的快速推进。

In order to ensure the safety of the 11-103 fully mechanized caving face of Huipodi Coal Mine passing through the old roadway in its mining range, based on the analysis of the layer relationship of the old roadway passing through the old roadway, two basic schemes for passing through the old roadway were proposed and determined, and the safety technical measures for the old roadway were also proposed. The practical application results show that this technical scheme has successfully guaranteed the safe passage of the 11-103 full-mechanized caving face through the old alley, realized the rapid advance of the working face.
