Abstract

In order to grasp the gas pressure distribution rule in coal and gas outburst risk prediction and study the methods for predicting coal seam gas pressure, the paper provides an effective basis for gas control. Through analyzing the gas pressure distribution in 7^# and 9^#close distance outburst coal seam of Linhuan Coal Mine, the gas pressure are predicted in different elevation zones. The results show that different regions have different pressure distribution between the weathered zone and the deep zone. More accurate predictions of gas pressure will be obtained through comprehensively considering the formula of geothermal and ground stress changes on gas pressure.
- gas pressure,
- distribution rule,
- pressure forecasting,
- weathered zone,
- hydrostatic pressure,
