突出矿井瓦斯抽采参数优化研究与应用

Study on the Optimization of Borehole Parameters for Gas Drainage in Outburst Mine

围绕突出矿井瓦斯抽采参数设定,进行了相应的理论计算。针对二景矿15205工作面,在充分考察不同钻孔间距抽采数据的基础上,通过分析比较不同试验区域瓦斯抽采达标时间,得到了抽采钻孔间距与抽采达标时间的关系。研究成果得到了成功应用和检验,为类似矿井瓦斯抽采参数优化提供了参考。

The relevant theoretical calculation is carried out based on the setting of gas extraction parameters in outburst mines.Aiming at 15205 working face of Erjing Mine,on the basis of fully investigating the data of gas extraction with different drilling spacing,the relationship between the drilling spacing and the time of gas extraction reaching the standard is obtained by analyzing and comparing the time of gas extraction reaching the standard in different test areas.The study results have been successfully applied and tested,which provides a reference for the optimization of extraction parameters of similar outburst mines.
