摘　　要：针对突水突泥这一矿山事故普遍存在于岩溶条件下的煤矿开采过程中的现象,文章开展了一系列突水突泥相似模型试验,探讨了泥水突出所具有的特点及影响突泥速度的2个因素,即储量和泥水压力。认为突泥过程一般可分为3个阶段,同时泥浆储量与泥水压力对突泥速度有很大影响。基于模型试验结果初步制定了煤矿巷道突水突泥防止措施。The mine accidents of water inrush and mud gushing commonly occur in the process of coal mining under Karst area.A series of similar model tests are carried out for the purpose of clarifying the characteristics of mud-water outburst and two factors influencing the velocity of slush,reserves and water inrush and mud gushing.Tests show that the process of water inrush and mud gushing can be divided into three stages,and the mud reserves and the mud-water pressure would also pose great impact on the velocity of the mud-water outburst.Based on the model test results,prevention measures for mud-water outburst in coal roadways are preliminarily formulated.
