摘要
为了确定综放面侧向支承压力分布,为沿空留巷煤柱宽度的确定提供参考,文章建立了计算模型。同时结合某矿2302工作面地质条件为背景,计算了工作面侧向支承压力计算,验证模型的正确性,分别计算厚表土层工作面、厚基岩工作面的侧向支承压力。结果表明,模型的提出能够准确地指导煤柱的留设,提高了生产效率。
In order to determine the lateral abutment pressure distribution of fully-mechanized face and provide referencefor the determination of the coal pillar width, the calculation model is established in the paper. At the same time, combinedwith the geological conditions of mine 2302 working face as the background, the working face lateral abutment pressurecalculation validates the correctness of the model, which calculates working face of thick overburden, thick face bedrocklateral abutment pressure. The results show that the proposed model can accurately guide the design of coal pillar andimproved the production efficiency.
