摘要
为解决“三下”压覆煤炭资源开采问题,以柴里煤矿3306东工作面为工程背景,系统介绍综采膏体充填开采的膏体材料配比及采-充工艺流程,并通过测点监测方法得出工作面回采对上覆地表铁路、公路及村庄、校舍等建(构)筑设施的影响均在I级损坏范围以内,验证了综采膏体充填工艺对“三下”压煤区域保护回采的实践效果。
In order to solve the problem of mining coal resources under"buildings,railways and water-bodies",taking the 3306 east working face of Chaili Coal Mine as the engineering background,this paper systematically introduces the paste material ratio and mining filling process of fully mechanized mining paste filling.Through monitoring methods at measuring points,it is found that the impact of mining on the overlying surface railways,roads,villages,schools and other buildings(structures)is within the scope of Level I damage,verified the practical effect of fully mechanized mining paste filling process on the protection and mining of"buildings,railways and water-bodies"coal pressure area.
