乌-奎高速公路煤层采空区注浆治理工程问题

Some problems of grouting engineering for coal gob area at the section of WuKui expressway

文章对煤矿采空区治理工程中的钻孔注浆问题进行了讨论。根据乌-奎高速公路上的具体实践,提出了钻孔注浆工艺的适用方法。从注浆过程、注浆材料等方面针对不同的注浆目的和地质情况,提出了改进的意见,克服了原设计在注浆施工中遇到的困难,解决了实际问题。

Some problems of bore grouting engineering for coal gob area are discussed in this paper. Some suitable motheds for bore grouting engineering are suggested according to the situation of the expressway at Wu-Kui section. According to the purpose of grouting and the geologic condition, some improving ideas on grouting process and material are put forward which overcomed the hardness and the problems in the grouting engineering and achieved all the goals.
