摘要
为了安全高效开采石炭二叠系特厚煤层,同忻煤矿结合矿区地质条件,确定了回采巷道锚杆、锚索联合支护技术参数,选择了适合该矿特点的回采工艺和合理的综放工作面支架支护强度,并采取了多种安全生产的技术措施,确保了同忻煤矿首采8101工作面的安全生产。
To mine extra-thick coal seam of Permian Strata safely and efficiently,based on the geological conditions of Tongxin Coal Mine,technology parameters of comprehensive supporting technology combined with bolt and anchor were determined.Reasonable coal winning technics and suitable supporting strength of supports on fully-mechanized top coal caving face were also chosen.A variety of safety production measures were taken to ensure the safety production 8101 first coal mining face in Tongxin Coal Mine.
