近距离煤层群上行开采可行性判定研究

Study on Feasibility of Near Distance Coal Seam Group Ascending Mining

从上行开采可行性常规判定方法的优缺点出发,提出了近距离煤层群上行开采可行性的判定准则,并利用数值模拟的方法进行了相关的分析与验证。针对现有的上行开采可行性判定方法存在一定的局限性,提出了新的判定方法,对工程应用有一定的指导意义。

This paper concludes advantages and disadvantages of feasibility of conventional judgment methods in ascending mining. The author proposes the judgment criterions for judging the feasibility of near distance coal seam group ascending mining and conducts correlation analysis and verification by employing the method of numerical simulation. Aiming at the certain limitation of the existing ascending mining judgment method has the author puts forward a new determination method hoping to bring instructive and meaningful results to engineering application.
