%X 为了加快经济发展方式转变,落实企业社会责任,全面开展绿色矿山建设,实现煤炭"绿色开采",同时解决煤矸石的堆积、矿井周边环境污染问题,提出了井下排矸的基本思路,探讨了井下排矸的意义、具体方法、适用条件和存在障碍。研究表明,采用合理的井下排矸分选设备与工艺流程,将毛煤进行井下预排矸,分选出的矸石进行有效回填,减少了原煤运输能耗,减轻了地上选煤负担,提高了煤炭利用率。而且,预排矸改善了矿区周边环境,增加了企业收益,但仍面临安全认证和生产问题。 In order to speed up the transformation of economic development and carry out the social responsibility,construct green mine with green mining technique,and solve the problem of coal gangue accumulation and pollution of the surrounding environment of mine,put forward some basic idea of removing gangue in underground mine. Discuss its significance,specific methods,applicable conditions and obstacles. The results shows that,pre-discharging the gross coal in underground mine with suitable washing equipments and process technology can reduce the energy consumption of coal transportation,ease the burden of coal processing and increase the utilization rate of coal. Moreover,the pre-discharging improves the surrounding environment of mining area and increases the corporate profitability. While the method also faces the problem of security certification and production
