摘要
针对赵各庄矿3237综放工作面,深部大倾角工作面瓦斯与煤层自燃综合防治中的裂隙场演化特征相似模拟,表明:上覆岩层在采动影响下会产生大量的离层和断裂裂隙;上覆煤岩层上的应力是动态变化的。提出了瓦斯的聚集区和瓦斯的运移规律。
For No.3237 fully-mechanized mining face in Zhaogezhuang mine, analog simulation was conduct on the evolvement characteristics of fracture field in the control of gas and coal seam spontaneous combustion on deep inclined fully-mechanized mining face. The results show that, under the mining impact, overlying strata would generate abundant separation and fracture. Besides, the stress of the overlying strata changes dynamically.
