Study on influence rules of gas extraction drilling borehole spacing on stress superposition effect

In order to study the rules of stress superposition effect and analyze the influence on the punching coal amount by borehole spacing, according to the general situation of Jiulishan Coal Mine and the actual situation of through-bed drilling construction, a solid mechanics model was established by us...
