曹庄煤矿随着生产能力的提高，开采储量逐年下降，煤炭资源枯竭，尤其是近几年为延长矿井服务年限，提高资源回收率，对一些受地质影响的煤柱工作面及煤矿开采初期遗留下来的煤炭资源进行开采。曹庄煤矿首次在下分层工作面应用综采工艺并实验成功，所有煤层均实现了综采工艺，通过对三层煤下分层推行新工艺、新技术，既实现了下分层工作面的高产高效，又对人工假顶下大断面巷道实现综采工艺的安装积累了经验。

Caozhuang coal mine with the improvement of production capacity, exploitation of reserves decline year by year, the coal resources drying up, especially in recent years to extend the service life of mine, improve the recovery rate of resources, to some affected by geological legacy in the early years of the working face and coal mining coal pillar mining of coal resources. Cao Zhuang coal mine next layered face fully mechanized process and experiment has been applied successfully for the ifrst time, coal seams are all realized process, based on three layers of coal layered to introduce new techniques, new technologies, both realized the layered working face under the high production and efifciency, and realize heavy seciton tunnel under the artiifcial roof installation of fully mechanized process accumulated experience.
