为研究南梁煤矿20203综采工作面矿压规律,通过实测工作面支架阻力、活柱下缩量、顶板移近量、顶板来压强度以及巷道变形参数等,获得了初次来步距、支架阻力的动载系数、老顶来压的强度等参数。研究结果表明:支架可以平衡顶板的压力,满足工作面开采时对支护强度的要求。总结了南梁矿浅埋煤层综采工作面的矿压显现规律,提出了提高支架初撑力等改善措施,为实现浅埋煤层综采工作面安全开采提供了可靠依据。
為研究南樑煤礦20203綜採工作麵礦壓規律,通過實測工作麵支架阻力、活柱下縮量、頂闆移近量、頂闆來壓彊度以及巷道變形參數等,穫得瞭初次來步距、支架阻力的動載繫數、老頂來壓的彊度等參數。研究結果錶明:支架可以平衡頂闆的壓力,滿足工作麵開採時對支護彊度的要求。總結瞭南樑礦淺埋煤層綜採工作麵的礦壓顯現規律,提齣瞭提高支架初撐力等改善措施,為實現淺埋煤層綜採工作麵安全開採提供瞭可靠依據。

Inorder to study the weighting law of 20203 face of Nan-Liang mine, the support resistance, the descending amount of piston, the main roof sink and the main roof intension are observed. The first weighting interval of main roof, the change coefficient of support and the weighting intensity are obtained. Field observation shows the support can balance the load of the rock and can meet the requirement of normal mining. The law of strata behavior in 20203 long-wall face of Nan-Liang mine in shallow seam is gained, and the support measure is put forward to improve the support state to prevent the disasters from occurring. This study provides the important science theory basis for realizing a safe mining in long-wall face in shallow seam.
