摘要
在承压水体上开采时,煤层底板突水过程是一个复杂的非平衡、非线性的演化过程。结合朱庄煤矿3629工作面实例,利用理论分析、相似材料模拟研究方法探讨了高承压水体上开采底板变形规律,解析煤层底板隔水层在采动矿压及底板含水层水压的复合作用下的破坏深度、应力传播特征、底板突水极限压力,并将解析解应用于朱庄煤矿3629工作面底板突水预测的实际工程中,取得较好的实际应用效果。
Mining on the top of water-pressured, the water inrush in coal floor is a complex nonequilibri- um and nonlinear evolution process. This paper applies the methods of theory analysis, similar material simulation to study the water invasion regularity in the floor mining on the top of water-pressured. The paper combined with the example of the 3629 working face in Zhuzhuang Coal mine, resolve the damage depth, the transferring character of the stress and the utmost pressure of water invasion in the floor of the water-resisting layer in the coal seam with the complex effect of the mining pressure and the water pressure in the floor water-resisting layers. The resolution is put into the project of the 3629 working face in Zhuzhuang Coal mine forecasting the water invasion in the floor which plays an important guiding role in mining the working face safely.
