【摘要】：根据《防治煤与瓦斯突出规定》的相关要求，结合红阳二矿开采实际条件，选择7煤层作为12煤层保护层。通过数据分析与现场实测，由于受采动影响，12煤层卸压瓦斯涌至7煤层，12煤层约有10m~3/t的卸压瓦斯，，上涌至7煤层排出。开采7煤层后12煤层可以得到较好的卸压保护效果。对西二采区的1201工作面和3701工作面回采期间瓦斯涌出规律进行了分析。得到了工作面绝对瓦斯涌出量随工作面推进度的关系，工作面日产量与工作面回风流瓦斯浓度随工作面推进度关系，工作面相对瓦斯涌出量随工作面推进度关系。为验证这些结论（规律）的准确性，进行了煤层瓦斯参数测定，主要包括煤层瓦斯压力、煤层瓦斯含量、瓦斯放散初速度、煤的坚固性系数值、工业分析、吸附常数等参数的测定分析。
[Abstract]:According to the relevant requirements of the regulation of coal and gas outburst, combined with the actual conditions of mining in Hongyang two mine, the 7 coal seam is selected as the 12 coal seam protection layer. Through data analysis and field measurement, due to the effect of mining, 12 coal seam pressure discharge gas Glock to 7 coal seam, 12 coal seam about 10m~3/t pressure relief gas and up to 7 coal seam. 12 coal after mining 7 coal seam. The layer can get better effect of pressure relief protection.
The law of gas emission during the 1201 working face and 3701 working face in the west two mining area is analyzed. The relationship between the absolute gas emission of the working face and the push progress of the working face is obtained. The relationship between the daily output of the working face and the gas concentration of the return air flow in the working face is related to the progress of the working face, and the relative gas emission of the working face is related to the progress of the working face. In order to verify the accuracy of these conclusions, the parameters of coal seam gas are measured, including coal seam gas pressure, coal seam gas content, gas discharge initial velocity, coal sturdy system value, industrial analysis, adsorption constant and other parameters.
