随着煤矿开采深度的增加，高地压、高水压煤矿破碎岩巷面的底鼓和突水灾害越来越多。为了研究这类巷道底鼓突水的机理和特征，采用相似模拟试验和巷道底板增压注水试验两种不同的方法，综合研究了深部巷道底鼓突水的临界突变规律。通过相似模拟试验，发现承压水扰动巷道底板破坏的特征。通过现场注水试验，分析了巷道底鼓量和底板岩石物性的变化规律，发现了深部巷道底鼓突水的突变性。
With the depth of coal mining increasing,more and more floor heave and water inrush hazards occur in the broken rocks roadway in the coal mine with high ground and water pressure.In order to study the mechanism and characteristic of this kind of roadway floor heave and water inrush,two different methods were accepted to study the critical mutation law of deep roadway floor heave and water inrush synthetically,which includes similar simulation test and water injection test by boosting pressure in the roadway floor.The characteristics of roadway floor failure disturbed by confined water was found by the similar simulation test.The change law of floor heave quantity and the floor rock physical property was analysed by the site water injection test,and the mutagenicity of the deep roadway floor heave and water inrush was found.
