衰老矿井边角呆滞煤开采方案设计研究

Resolution to Corner Coal Exploitation Scheme of Aged Coal Mine

依据三环剩余可采储量的资源赋存特点,设计了探煤巷掘进采煤、小采面跳采、边界煤层联合布置等开采方案,方案的成功实施证明能够改善采掘关系、提高矿井回采率、延长矿井服务年限。

It gives different schemes for different comer coal according to its occurrence conditions and feasibility analysis of the left available coal resource, such as coal - laneway exploration method, small working-face skip - mining method, combined boundary coal layout mining method. And it brings out much virtues for the aged coal mine, bettering relation between mining and excavatioin, reducing coal production cost, enhancing recovery ration, extending service life consequently.
