摘要
针对煤炭开采后采空区会造成地质、环境、社会及资源等一系列原生和次生灾害的问题,提出利用充填材料对采空区进行充填处理的采煤方法,就充填材料特性的影响因素,充填开采技术的发展,充填材料决定充填开采工艺与效益,及膏体材料是充填材料未来的发展方向作了简要介绍。
The current major coal mining methods will cause a series of primary and secondary issues such as geological,environmental,social and resource and hinder the sustainable development of coal mining.Based on green mining concept,using cheap filling materials,backfill mining could achieve the purposes of environmental protection,water conservation and improving recovery rate.By analyzing the backfill material properties and backfill mining technology,the paste material is the future development direction of the filling material.
