在煤与瓦斯突出中,采煤工作面所占的比重约在10%左右,而因回采工作面空间小,工作人员相对集中,机器设备复杂,人员撤退困难,所以,一旦煤与瓦斯突出,对人身安全产生威胁很大。因此,采煤工作面的防突工作非常重要。现主要阐述了松动爆破、长钻孔控制卸压爆破、浅孔注水湿润煤体等采煤工作面防突措施等问题。
In coal and gas outburst, coal mining face accounted for about 10% of the proportion, but due to small working face mining space, the relative concentration of staff, complex machinery and equipment, personnel retreat difficult, so once the coal and gas outburst, On the personal safety threat. Therefore, the work of the coal face to prevent outbreak is very important. Now mainly expounded the loose blasting, long borehole control pressure relief blasting, shallow hole wetting coal and other coal face prevention measures such as outburst.
