Abstract: In order to discuss how hydraulic punching process influences the neighboring punching holes and gas emission during the heading faces, the study aims at the gas overrun accident during the hydraulic punching process in Zhongma Coal Mine, the paper researches the boreholes design, the coal amount of hydraulic punching and gas overrun process during the construction. In the end, conclusion is that under the same coal seam occurrence condition, the relationship among the coal, amount of punching, hole range and construction intervals should be taken into consideration when hydraulic punching is used to increase the permeability and creep degree of the coal rock. Otherwise, the gas of neighboring holes and construction sites are vulnerable to influence each other.
