| 摘 要： | 水力掏槽措施可在突出煤层中实现快速掘进,但在掏槽过程中仍然会存在突出的现象,尤其是在槽硐中会产生小的突出,为控制这一现象的发生,改善水力掏槽措施,从引起槽硐周围煤体突出的根源入手,运用宏观突出理论,分别从瓦斯内能、顶底板弹性潜能和煤体弹性潜能三个方面对槽硐突出能量进行深入分析。并结合黑龙江省矿区煤层、瓦斯赋存等实际情况,进行定量分析。对掘进工作面槽硐突出能量的研究可拓展水力掏槽措施防突机理,并提高水力掏槽措施在黑龙江省矿区的适应性。

| Abstract: | Quick tunneling can be realized in outburst coal seam by hydraulic cutting measure. But the outburst phenomenon remained during cutting, the small outburst emerged especially in the hole. The hydraulic cutting measure should be improved to avert the outburst. From the source of outburst of coal around the hole, the quantity of outburst energy of the hole was analyze deeply on the intrinsic gas energy, the elastic potential energy of roof and floor and the coal by macroscopical outburst theory. And the quantitative analysis was made according to coal seam and gas occurrence of mining area of Heilongjiang Province. The research of this paper expands the outburst protection mechanism of hydraulic cutting measure and enhances the adaptation of the measure applied to minin area of Heilongjiang Province. |
