本文主要介绍国内外倾斜长壁采煤法的使用概况及发展趋势。

The paper gives a brief account of the use and developing tendency of the inclined longwall coal-mining at home and abroad .

倾斜长壁采煤法经过几十年的试验和研究推广，逐渐成为开采倾斜煤层的重要发展方向之一。

After decades of examination and extension , Inclined long-wall mining had became one of the important mining methods for inclined coal seam .

近距离煤层的上部煤层采用刀柱采煤法回采后，下部煤层采用长壁采煤法进行回采。

In the upper seam of close distance coal seams pillar mining method is utilized , and in the underneath seam prepared to be mined long wall mining method is utilized .

但随着采煤机械化的发展和对提高资源回收率的要求，多数条件下已逐步向长壁冒落采煤法转变。

However , with the development of integrated mechanization and the request of improving the recovery rate , most of the conditions have been changed gradually to the long-wall mining method .
