摘要:
采用水力压冲技术,在区域防突措施钻孔施工前先对原始煤体进行水力掏穴,冲出大量煤体和瓦斯,对原始煤体进行卸压增透,以增加煤层的透气性系数,再对卸压后的煤体施工区域防突措施钻孔。将此技术应用在新庄孜煤矿-812 m南边界石门揭B11b煤层中,使得B11b煤层原始瓦斯压力由2.8 MPa降到1.2 MPa,原始瓦斯含量由12.31 m3/t降到8.5 m3/t,煤层透气性系数由原来的0.004 83 m2/(MPa2·d)增加到0.683 1 m2/(MPa2·d),水力压冲共计冲出煤粉量285 t,区域措施钻孔瓦斯抽采浓度达35%,瓦斯抽采总量135 316.8 m3,抽采率63.9%,既缩短了揭煤工期,又保证了揭煤施工过程中的安全。
Abstract:
We adopted the hydraulic pressure rushing technology in -812 m southern border rock cross-cut of Xinzhuangzi Coal Mine,in which the water with high pressure was used to press the original coal body before the construction of the regional drilling hole,rushing out a large amount of coal and gas,relieving the pressure of original coal seam and improving its permeability. As a result, the original gas pressure of B11b coal reduced from 2.8 MPa to 1.2 MPa,the original gas content decreased from 12.31 m3/t to 8.5 m3/t,and the permeability coefficient of coal seam increased from 0.004 83 m2/(MPa2·d) to 0.683 1 m2/(MPa2·d). In the process of hydraulic pressure rushing,285 t of coal powders were rushed out,the gas concentration reached 35% by drainage and extraction during regional measures,63.9% of gas was collected with the total amount of 135 316.8 m3,The hydraulic pressure rushing technology not only shortens the time but also guarantees the safety in the process of uncovering coal.
