摘要
正断层附近煤层的孔隙、裂隙是与正断层的形成过程密切相关的,通过对正断层附近煤层的孔隙、裂隙特征及煤的机械性能的分析,在煤矿生产实践中指导煤与瓦斯突出的预测、瓦斯资源抽放利用的评价、隔离煤柱宽度的计算。
The pores and cracks in coal seam nearby the normal fault are closely correlated to the forming process of the normal fault. By the analysis of the characteristics and mechanical property of the pores and cracks in coal seam nearby the normal fault, instructs the forecast of coal and gas outburst, the appraisal of the gas resources drainage and utilization, and the calculation of the width of separating coal wedge.
