基于矿井通风与超前预抽的瓦斯综合治理技术研究

Study on Comprehensive Gas Control Technology Based on Mine Ventilation and Advance Prepumping

为进一步保证深部煤层开采的安全性,确保其瓦斯浓度满足《煤炭安全规程》的相关规定尤为重要,本文在测定2302工作面瓦斯参数的基础上得出了该工作面瓦斯的最大涌出量,在当前工作面正常通风的基础上,确定超前预抽的钻场和钻孔参数,最后,通过实践生产验证了超前预抽采方式达到综合治理瓦斯水平的效果。

In order to further ensure the safety of deep coal seam mining and ensure that its gas concentration meets the relevant provisions of the“Coal Safety Regulations”,it is particularly important to determine the maximum gas emission from the 2302 working face based on the measurement of gas parameters.Based on the normal ventilation of the current working face,the drilling field and drilling parameters for advance prepumping are determined.Finally,the effectiveness of advance prepumping method in achieving comprehensive gas control level was verified through practical production.
