摘要：【中文】本发明提供一种具有突出危险煤层的巷道最佳掘进速度的判定方法。通过现场观测得到巷道不同掘进速度下前方煤体内应力分布曲线图及瓦斯压力分布曲线图，利用回归分析方法得到掘进巷道前方煤体内应力峰前区应力大小及瓦斯压力大小分别与距巷道掘进工作面距离之间的函数关系式。依据函数关系式，利用积分的方法求出煤与瓦斯突出的能量源，确定煤体破碎和移动所需要消耗的能量。最后求出巷道不同掘进速度下，煤与瓦斯突出能量源与煤体破碎和移动所消耗能量的比值。在所有比值小于1所对应的巷道掘进速度中，最快的巷道掘进速度即为具有突出危险煤层的巷道最佳掘进速度。本方法具有应用简单，投入成本低、使用方便，判定结果可靠等优点。 【EN】The invention provides a method for judging the optimal tunneling speed of a roadway with a outburst dangerous coal seam. And obtaining an internal stress distribution curve chart of the front coal body and a gas pressure distribution curve chart under different tunneling speeds of the tunnel through field observation, and obtaining a function relation between the stress of the front area of the internal stress peak of the front coal body in the tunneling tunnel and the distance between the front coal body and the tunneling working face of the tunnel and the gas pressure by using a regression analysis method. And (4) solving an energy source of the coal and the gas protrusion by utilizing an integral method according to the functional relation, and determining the energy consumed by the coal body crushing and moving. And finally, the ratio of the energy sources of the coal and the gas outburst to the energy consumed by the crushing and moving of the coal body is calculated under different tunneling speeds of the tunnel. And in the tunneling speeds corresponding to all the ratios smaller than 1, the highest tunneling speed is the optimal tunneling speed of the tunnel with the outburst dangerous coal seam. The method has the advantages of simple application, low investment cost, convenient use, reliable judgment result and the like.
