为解决补连塔煤矿12煤五盘区综采工作面矿压显现剧烈的问题,对12519综采工作面的矿压显现情况进行了总结,得到了矿压显现的规律及其与工作面冒顶、片帮的关系。研究发现,引起综采工作面冒顶、片帮的主要原因是液压支架工作阻力不足、液压支架工况差、液压支架长期处于非正常工作状态及冒顶与片帮的相互影响,在采取了工作面加快推进速度、顶板加固锚索、顶帮加固高分子材料等对策后,保证了工作面的顺利回采。
In order to solve the problem of drastic underground pressure in fully mechanized coal face of 12 coal in Well Pian Tata Coal Mine, the occurrence of mine pressure in 12519 fully mechanized coal mining face is summarized, and the regularity of mine pressure and its relationship with roof fall , The relationship between the film to help. It is found that the main causes of the roof falling and the sheet bosking in the fully mechanized mining face are that the working resistance of the hydraulic support is insufficient, the hydraulic support is in poor working condition, the hydraulic support is in a non-normal working state for a long time and the interaction between the roof and the sheet support is taken, Accelerate the speed, the roof reinforcement anchor cable, top to help strengthen the polymer materials and other countermeasures to ensure the smooth mining face.
