The article introduces the mining coal working face false inclines the necessity which the arrangement,returns picks,flings the slanting plan through the formulation science,takes the efficient technical measure,solves the irregular mining coal working surface to return picks in the process to fling the slanting question,returns to the similar working face picks has the certain model function.
介绍了采煤工作面伪倾斜布置及回采的必要性,通过制定科学的甩斜方案,采取得力的技术措施,解决了不规则采煤工作面回采过程中的甩斜子问题,对同类工作面的回采有一定的借鉴作用。
In order to reduce the coal loss and increase the rate of recovery,the new mining methods are adopted,which is false inclination mining,top tunnel outward mining,and bottom tunnel outward mining.
为了减少煤炭损失,提高回采率,采取新的回采方式,即伪倾斜开采和上巷前进式、下巷前进式回采,使煤炭损失量降低到最小程度,提高了经济效益。
