大倾角煤层走向长壁综采(放)工作面上端头存在着顶、底板三角区。上端头采用抬棚、基本架或端头支架支护。工程实践表明,采用端头支架支护方式解决了大倾角走向长壁综采(放)工作面上端头支护技术难题,取得了良好的支护效果,降低了劳动强度,确保了上端头的安全,提高了生产效率。
Steeply inclined coal seam toward the longwall fully mechanized (release) working face there is the top of the top, floor triangle. The upper end of the lift shed, the basic frame or end bracket support. The engineering practice shows that the technical support for the upper end support of longwall fully mechanized (fully mechanized) mining face with a large dip angle is solved by adopting the end support support method, good support effect is obtained, the labor intensity is reduced, the upper end Safety, improve production efficiency.
