泉店煤矿11采区二_3煤层突出危险性区域预测

Regional Prediction of Outburst Dangerous on No.2_3 Coal seam of Quandian Coal Mine No.11 Mining Area

为了对泉店煤矿11采区二3煤层进行突出危险性区域预测,对其瓦斯压力、煤的坚固性系数、瓦斯放散初速度、瓦斯含量等瓦斯基础参数进行了测定,根据测定结果,依据《防治煤与瓦斯突出规定》和《煤与瓦斯突出矿井鉴定规范》等规定,确定11采区二3煤层为非突出煤层。

In order to predict scientifically and rationally outburst dangerous regional in No.23 coal seam of Quandian coal mine No.11 mining area,the gas basic parameters such as gas pressure,firmness coefficient of coal,initial speed of methane diffusion,gas content were measured.According to measured results and relevant regulations of specification for coal and gas outburst prevention and specification for Identification of coal and gas outburst mine,No.23 coal seam of No.11 mining area was determined to non-outburst coal seam.
