大倾角软厚煤层不对称褶曲构造综采工艺研究

陈蛮庄矿井3206工作面倾角大、煤层软、工作面内赋存褶曲构造,为全国首个此类条件综采面,主要工艺难题是支架下滑、歪架、煤矸滚落、煤机自重下滑、煤机下行割煤自行加速,易片帮和端面距过大以致面前顶板冒落,褶曲坡度变化段挤架、咬架和歪架,造成刮板输送机不平直、上漂等一系列问题。通过严谨的"三机配套"选型、合理的采煤工艺及严密的施工组织和科学管理,保证了同等条件下的稳产高产。

Chen manzhuang mine 3206 working face of large dip Angle, soft coal seam, the working face in occurrence fold structure, for the first such conditions of fully mechanized face, the main technical problem is stent decline, slanting frame, weight of coal waste tumbled, coal drop, coal to accelerate downward cut coal, easy to help and face away from too much so that the front roof caving, fold gradient change period of crowded shelves, bite and slanting frame, causing floated on scraper conveyor is not fiat, and a series of problems. Through rigorous supporting these compressors ＂selection, reasonable mining technology and strict construction organization and scientific management, ensure the production stable high yield under the same conditions.
