金辛达煤矿201胶带顺槽切顶卸压技术的应用研究

Application Research of 201 Belt Cutting and Roof Pressure Relief Technology in Jinxinda Coal Mine

为了改善金辛达煤业的采掘接续紧张以及应力集中现象显著的现状,以及解决薄煤层沿空留巷围岩变形严重的问题,在分析金辛达煤业201工作面地质概况的基础上,将更优良的聚能预裂切缝技术应用到了金辛达煤矿中201工作面顺槽切顶卸压施工工艺中,并对实验结果进行效果评价,验证了此设计方案的可行性及经济性,有效提高了煤炭回收率。

In order to solve the current situation of tight mining continuity and significant stress concentration in Jinxinda Coal Industry,and the problem of serious deformation of surrounding rock in thin coal seam gob-side entry retaining.On the basis of analyzing the geological overview of the 201 working face of Jinxinda Coal Mine,the better energy-gathering pre-splitting cutting technology was applied to the construction technology of the 201 working face along the groove in the Jinxinda Coal Mine,and the experimental results were compared.The effect evaluation is carried out to verify the feasibility and economy of this design scheme,which can effectively improve coal recovery.
