摘要
根据孤岛工作面生产地质条件,建立了深部孤岛工作面采场力学结构模型,对非对称孤岛工作面形态进行了分析,通过理论分析确定了较为合理的支护方式以及支护参数,并且在实践当中进行了回采巷道的实测研究。
In this paper, the geological conditions of the production, the roadway support principle and influence factor were introduced, has carried on the analysis to the non symmetric isolated working face shape, the stope structural mechanics model of the deep isolated working face is set up, by the theoretical analysis, the reasonable support method and support parameters were determined, and the experimental study on roadway were carried out in practice.
