杜家沟煤业2号煤层反顺序开采可行性研究

Feasibility Study on Reverse Sequential Mining of No.2 Coal Seam of Dujiagou Coal Industry Co.,Ltd

杜家沟煤业有限责任公司2号煤层下部10号煤层已先行完成开采,当前由于采掘需要,需对2号煤层进行开采。从杜家沟煤业有限责任公司2号煤层的蹬空情况入手,通过现场调研、理论分析等多种研究手段,对2号煤层反顺序开采的可行性进行了论证与评价,对反顺序开采工作面及其回采巷道进行了合理布置,并提出了相应的安全技术措施。

The No.10 coal seam under the No.2 coal seam of Dujiagou Coal Industry Co.,Ltd.has been mined first.Due to mining needs,the No.2 coal seam needs to be mined.Starting from the kick-off situation of No.2 coal seam of Dujiagou Coal Industry Co.,Ltd.,through field investigation,theoretical analysis and other research methods,this paper demonstrated and evaluated the feasibility of reverse sequential mining of No.2 coal seam.The reverse sequential mining face and its mining roadways were reasonably arranged.The corresponding safety technical measures were proposed.
