摘要
泉店煤矿二1-12050综放工作面地质条件复杂,回采过程中,随着工作面的推进,工作面长度逐渐增加,由设计时的153 m延长至159 m,增加了机尾空顶面积。为保证正常推进,工作面机尾处需延设输送机和支架。通过现场研究与分析,确定了待安装支架的数量与位置,达到了科学、快速、合理延长工作面的效果,提高了综放工作面的机械化生产能力和煤炭资源采出率。
The geological conditions on Ⅱ1-12050 fully-mechanized top coal caving face in Quandian Coal Mine are complex.With the face forward,face length increased gradually from the design of 153 m to 159 m in recovery process,and the empty-support area of conveyor tail was added.To ensure normal progress,conveyors and supports were required to install at the tail part of working face.The number and location of supports waiting for being installed were determined through field research and analysis.All this have reached the scientific,quick effect of extending working face,and enhanced the production ability of fully-mechanized top coal caving face,its recovery ratio was increased,too.
