摘要
孤岛工作面围岩结构由于受到两面采空区的影响,回采过程中其原岩应力场逐渐被弱化,围岩控制较为困难。本文以金晖荣泰煤业10209(2)孤岛工作面为研究对象,研究了回采巷道围岩控制技术的支护方案,实际应用后表明该支护方案可以有效地保证巷道围岩的稳定性,确保了10209(2)回采工作的正常进行。
Due to the influence of the goaf on both sides of the surrounding rock structure of the isolated island working face,the original rock stress field is gradually weakened during the mining process,and the surrounding rock control is difficult.This paper takes Jinhui Rongtai Coal Industry 10209(2)isolated island working face as the research object,and studies the support scheme of the surrounding rock control technology of the mining roadway.After practical application,it shows that the support scheme can effectively ensure the stability of the roadway surrounding rock.It ensures the normal progress of the 10209(2)stoping work,which is of reference significance for the mining of isolated island working faces under the same conditions.
