| Abstract: | The parameters of time and space, such as the districts of increasing and decreasing pressure, the effective range and time of the influence and the blasting process etc. have gotten accordingly as the unloading effect by blasting in wall knife-pillars face in seam 2 in Men Tou Gou colliery is detected using Type KS-1 stressmeter and method of drilling slack. Therefore, the unloading by blasting which is a convention and effective measure of prevention and remedy rock-bursts can get quantitative research. |
