摘要
Abstract
The mining in the working face of the close coal seam is affected by dynamic pressure, so the mining is difficult, and the everyday efficiency is quite low. To solve the problem, the advanced supporting, end support, end bracket matches, coal mining technology, the two end maintenance,and the layout of train equipment are improved, which realizes safe production and the rational mining operation cycle. The technology improvement is mainly suitable for coal face in such special cases as thin layer spacing, loose roof, easily broken, easy leaking roof, unroofed network laid etc, which achieved good effect.关键词
