防止瓦斯抽采孔垮塌的方法技术

本发明专利技术公开了一种防止瓦斯抽采孔垮塌的方法，属于综合治理煤矿瓦斯的安全技术；旨在提供一种既能够避免瓦斯抽采孔垮塌、又不妨碍从煤层中抽采瓦斯的方法。具体方法是：将若干多孔陶瓷颗粒填充于瓦斯抽采孔中，然后埋插入瓦斯抽放管，用封孔材料将所述瓦斯抽采孔的孔口封闭。本发明专利技术不仅彻底克服了瓦斯抽采孔容易垮塌而造成堵塞的缺陷、有效地延长了瓦斯抽采孔的服务期限，而且不会妨碍瓦斯的顺利抽采，具有操作简单、施工方便、成本低、安全可靠等很多优点；是综合治理煤矿瓦斯的一种理想方法。

Method for preventing collapse of gas extraction hole

The invention discloses a method for preventing gas drainage hole collapse, which belongs to the safety technology of coal mine gas comprehensive management; aims to provide a method which can avoid the mining hole collapse, gas drainage and gas drainage from the seam does not interfere with the. The concrete method is that a plurality of porous ceramic particles are filled in the gas extraction hole, and then buried into the gas drainage pipe, and the orifice of the gas extraction hole is sealed with a sealing hole material. The invention not only overcomes the gas drainage hole is easy to collapse and blockage caused by defects, effectively prolong the service period of the gas drainage hole, and will not hinder the smooth gas drainage, has the advantages of simple operation, convenient construction, low cost, safe and reliable and so many advantages; is an ideal method for the comprehensive management of coal mine gas the.
