    • Abstract
  • Fracturing of faults affects the coalbed gas content and gas-gushing volume during mining.In this paper,the basic gas-gushing characteristics on both sides of small faults in Renlou Coal Mine,Wanbei are analyzed.It is presented that the gas-gushing volume is well consistent to where it is affected by fault through comparing the gas-gushing volume of affected zones to that of normal zones.The results of statistics analysis show that the fall of faults is in good pertinence with the distance between where the peak of gas-gushing volume is occurred and the rupture of the faults,that the scope of abnormal gas-gushing zone has a linear relation with the fall of faults,that the distance between the gas-gushing peak occurring spot and the rupture of faults,the scope of abnormal zone are 35 times and 60 times the breadth of the fall respectively.
