摘要
煤矿瓦斯浓度超标是煤矿生产过程中,发生灾害的重要因素,直接威胁煤矿安全生产。近年来,高瓦斯矿井大多进行地面瓦斯抽放钻孔施工,通过地面抽放的方式,降低采区瓦斯浓度,保障安全生产。以淮北矿业集团朱仙庄煤矿大口径瓦斯抽放钻孔施工为例,详细叙述了大口径瓦斯抽放钻孔施工工艺及应用实践,对同类工程施工具有重要的借鉴意义。
The gas concentration exceeding the standard is an important factor to occur a mine disaster in the production process in a coal mine,and it would directly threaten the mine safety production.In recent years,the gas drainage boreholes were drilled from ground in most highly gassy coal mines,and the mode of drawing gas on the ground was used to reduce the gas concentration in the mining block in order to ensure the mine safety production.Took the large diameter gas drainage boreholes construction in Zhuxianzhuang Coal Mine of Huaibei Mining Group as an example,the construction technology and the application practices of the large diameter gas drainage borehole was narrated in detail,and it could provide the important reference significances to the similar engineering construction.
