兖州矿业(集团)公司东滩煤矿综放工作面切眼沿空布置,在143上06(西)、43上12等综放工作面应用中取得了很好的效果。采用大断面导硐,充分利用巷道断面,合理布置锚索和单体液压支柱,增强了整个切眼的整体支护效果。在导硐的时候,将带式输送机置于扩宽侧,掘进机倒骑于带式输送机,避免了扩宽的时候再次铺带式输送机。导硐施工到位以后,采用新的施工工序,比以前掘进机不后退、直接摘掉转载机调头施工、边掘边加转载机的施工方式节省了大量的时间和劳动力。在掘进机调
The fully mechanized Caving Face of Dongtan Coal Mine of Yanzhou Mining (Group) Co., Ltd. was cut off along the road and achieved good results in the application of fully mechanized caving mining works such as 143 Shang 06 (West), 43 Shang 12 etc. The use of large cross-section of the tunnel, make full use of the tunnel section, reasonable arrangement of anchor and single hydraulic props, enhance the overall cut eye overall support effect. In the guide cave, the belt conveyor is placed on the widening side, and the roadheader is mounted on the belt conveyor to avoid the belt conveyor being widened again. After the construction of the guide tunnel is in place, the new construction procedure is adopted, the tunneling machine is not withdrawn from the original construction of the loader and the construction method of the boring and adding of the loader can save a lot of time and labor. In the boring machine tune
