鹤岗矿业集团公司新兴煤矿随着开采深度的增加,矿山压力增大,地质构造复杂,旧的开采工艺已不能适应生产和安全的要求。该矿根据煤层赋存特点,选用并联顶梁支架,通过近半年的试采,取得了良好的效果。
The older exploit way has already can't adapt to the request of the production and safety in Xinxing Coal Mine,Hegang Mining Group Company,which by with the increasing of the exploitation depth and the accretion the press of mine and complexity of the soil mass constitution.So the parallel connection tip girder support is chosen and applied according to the characteristics of the coal mine.Trying to exploit by this way through half year,the good result is obtained.
