在井简开凿工程中,遇到断层、软岩、细小裂缝含水层等复杂的地质条件,需要堵水与加固。国外通常采用磨细水泥或化学浆液作为注浆材料。而对于我国来说,这种材料存在货源、经济及污染等问题。本文则介绍了使用普通水泥浆的注浆方法,几年来在煤炭系统试验中已取得较好效果。文中结合九龙口矿北风井、开滦钱家营矿副井、林南仓矿副井等应用实例,阐述了使用普通水泥浆堵水、加固的几种方法:压裂法、预处理法、同层钻进交替注浆法以及这几种方法相结合的综合法。其中,压 In the well drilling project, encountered complex geological conditions such as faults, soft rocks and fine cracks aquifers, water blocking and reinforcement are required. Foreign countries usually use ground cement or chemical grout as grouting material. For our country, this material exists in supply, economic and pollution problems. This article describes the use of ordinary grouting grouting method, the coal system in recent years has achieved good results in the test. Combined with the application cases of Beifeng well of Jiulongkou Mine, Qianjiaying Mine of Kailuan Mine and the auxiliary well of Linnan Mine and Mine, several methods of using ordinary slurry to block water and reinforce are expounded: fracturing method, pretreatment method, Drilling into the alternating grouting method and a combination of these several methods. Among them, pressure
