采煤工作面

So integrating with all these advantages of mechanized coalmining is the development direction of production technology of coal industry stope.

综合机械化采煤具有产量大、效率高、成本低、改善作业环境、减轻笨重的体力劳动等优点，是煤炭工业回采工作面生产技术的发展方向。

With the development of technology, automation of fully mechanized sublevel caving working face now becomes a main trend of modern mining.

随着生产技术水平的不断提高，综放工作面自动化是现代采煤发展的一个必然趋势。

Therefore, the scraper conveyer delivery capacity has decided the mining coal working surface productivity and the efficiency in a great degree; however, our country was lagged behind at present; the scraper conveyer installing equipment power is small.

刮板输送机是综采工作面配套设备的重要组成部分，是煤炭装运的第一个环节。因此，刮板输送机的输送能力在很大程度上决定了采煤工作面的生产能力和效率。

Based on the geological and mining conditions and occurrence characteristics of loose aquifer of Xinglongzhuang Colliery,water bursting cause of 4303 full-mechanized caving mining face under loose aquifer was analyzed,the prevention measures of the 3rd aquifer and reasonable dimension of coal pillar for sand proof were discussed in this paper.

通过对梅河四井溃泥工作面覆岩破坏特征和顶板岩层状态的探测分析，结合离散元数值模拟手段，模拟了不同状态顶板条件下水平分层综放开采的顶底板位移场和破坏场，探索了溃泥、溃砂发生的成因和机理，丰富了水体下采煤的理论和技术体系。

To settle the traditional conflict between aquifer protective mining, and to enhance the coal recovery ratio to the maximum, based on the protection mining technique in longwall coalface with rapid mining.

为解决浅埋煤层保水与采煤这一矛盾，并最大限度的提高煤炭资源回收率，神东矿区上湾煤矿51201大采高长壁综采工作面进行了保水开采工业性试验。
