6.5m高架综采工作面大角度仰采关键技术研究

6.5m Elevated Fully Mechanized Working Face Wide-angle Overhead Mining

东庞矿2612综采工作面安装并使用6.5m综采支架及配套设备,由于向斜构造的存在,工作面在回采后期由俯采逐步转变为大角度仰采,仰采角达15°,结合2612工作面的实际情况,分析煤壁稳定性及其影响因素,提出控制煤壁片帮和端面冒顶的技术措施,保证工作面的安全生产。

2612 fully mechanized working face of Dongpang Mine used 6.5 m fully mechanized mining support and corollary equipment, because of the syncline structure, in the late period of working face recovery, mining gradually transformed from underhand stoping into overhead mining, overhead angle with 15° , combined with the actual situation of 2612 working face, the coal wall stability and its influencing factors were analyzed, technical measures of controlling rib spalling and top earing were put forward, which ensured the safe production of the working face.
