摘要
针对新驿矿井煤层含矸率高和村庄压煤较多的实际情况,提出了在井下建设选煤系统和充填系统,该系统有效地解决了矸石升井占地和地面塌陷的问题,既提高了煤炭质量,又避免了对环境的污染,为今后类似条件矿井绿色开采之路提供了经验借鉴和技术保障。
According to the actual situation of high gangue rate and the more village coal in Xinyi Coal mine, put forward the construction of coal preparation system and iflling system in underground, the system effectively solves the gangue covering and ground subsidence problems, which can not only improve the quality of coal, but also avoid the pollution to the environment, and provided experience and technical support for mine green mining with similar conditions in future.
