针对王庄煤矿面临的村庄压煤和提高开采上限等问题,结合目前充填技术及煤矿实际开采情况,引进了矸石充填采煤技术。简介了该矿井的地质概况及充填系统具体内用,并对其产生的经济、社会效益进行了分析。利用泵送设备通过管道把膏体充填材料有井下泵送至采煤工作面,及时充填采空区,达到矸石不升井,绿色开采。
In view of the problems such as the coal pressing in the village facing Wangzhuang Coal Mine and the raising of the upper mining limit and so on, the technology of waste rock filling coal mining was introduced in combination with the current filling technology and the actual mining situation in coal mines. This paper briefly introduced the geology of the mine and the specific internal use of the filling system, and analyzed its economic and social benefits. Use of pumping equipment through the pipeline to the paste filling material downhole pumping coal mining face, filling the goaf in time to achieve the gangue not raise wells, green mining.
