突出煤层掘进工作面综合防突措施研究
|
摘要
为了防止突出煤层巷道掘进期间发生煤与瓦斯突出事故,保证巷道掘进安全,山西新元煤炭有限责任公司通风部防突队通过技术研究,对3#煤层一水平四采区3412进风巷掘进期间,采取"瓦斯预抽+超前卸压+钻孔注水+松动爆破"等联合方法进行综合防突,并对其应用效果进行检验,实践证明取得了显著成效。
In order to prevent the accidents of coal and gas outburst occurring during the excavation of the coal seam roadway and ensure the safety of the tunnel excavation, the anti outburst team of the ventilation Department of the Shanxi Xinyuan coal limited liability company has adopted the technical research. The "gas pre pumping + preloading + pressure unloading + drilling water injection + loosening blasting"was adopted during the 3412 entry road heading in the one level and four mining area of the 3# coal seam. Combined with other methods, the comprehensive outburst prevention has been carried out, and its application effect has been tested. Practice has proved that remarkable results have been achieved.
