基于水力冲孔的回采工作面快速卸压消突技术研究
|
摘要
为了确保煤巷掘进安全、高效和工作面的顺利投产,采用水力冲孔技术,对掩护煤矿掘进和回采的区域预抽钻孔进行强化抽采,研究了水力冲孔影响半径以及冲孔后钻孔预抽效果。研究得出:采用水力冲孔技术后,2713底板抽放巷水力冲孔影响半径在7 d后可以达到4.9 m,在10 d后可以达到5.7 m,在17 d后可以达到8.9 m,随后趋于稳定,抽放时间缩短为原来的一半;在40 d内水力冲孔效果达到极限;煤层透气性增加了约11.4倍,研究为类似低透气性高瓦斯突出煤层的高效安全瓦斯治理和安全生产提供技术支持。
In order to ensure the safe and efficient excavation of coal roadway and the smooth operation of working face,the hydraulic punching technology was adopted to strengthen the pre-pumping borehole in the tunneling and recovery of coal mines. The influence radius of hydraulic punching and pre-pumping effects of drilling after punching were also studied in this paper. The results showed that:after hydraulic punching,the impact radius of hydraulic punching in pumping drainage of 2713 floor can reach 4. 9 m after 7 days,5. 7 m after 10 days,8. 9 m after 17 days,and then stabilized. The drainage time can save half of the time. Within 40 days,the hydraulic punching effect reached the limit. The gas permeability of the coal seam increased by 11. 4 times. The study provides technical support for efficient and safe gas control and safety production of low permeability gas outburst coal seam.
