摘要
针对我国建筑物下压煤量大以及地面矸石堆积污染环境的现状,文章以峰峰集团羊东矿建筑物下压煤为例,通过数值模拟确定充填巷宽度和隔离煤柱宽度,并对地表沉陷进行了预计。结果表明:建筑物下矸石充填技术能够很好的解决环境污染问题并提高采出率,该技术的应用研究为矿山开采增加新的技术方法,进一步加速了生态矿山建设进程,真正实现煤矿的可持续发展。
Aiming at the actuality of plentiful pressed coal under buildings and environment polluted by the piled coal refuse on the ground in our country, this paper takes Yang Dong coal mine of Fengfeng group under building as an example, filling lane width and isolation coal pillar width, are determined by numerical simulation. The resuhs show that the coal refuse backfilling technology under building can be good to solve the environmental pollution and raise recovery rate. Application of refuse backfilling technology carries out new mining technology and methods, to accelerate the process of building eco - mine and to achieve the sustainable development of mining industry. As the increasing of this mine＇s production, it can bring to mine district with remarkable economic and social performance.
