鲁新煤矿火成岩含水层特点与地面预注浆治理

Characteristic of igneous rock aquifer and treatment of ground advance grouting in Luxin coal mine

鲁新煤矿主井基岩段全部为火成岩,其裂隙发育特点和含水层特征与成岩过程密切相关,本文以此为例探讨了全孔段火成岩条件下井筒地面预注浆的措施和技术特点,并对注浆参数的变化规律和注浆效果进行了分析,可供类似工程参考。

The bedrock section of main shaft in Luxin coal mine is entirely structured with igneous rock, and its fissure development and aquifer characteristics are closely related to diagenetic process. Based on the project, the measures and technical characteristic of pit shaft＇s ground advance grouting under the condition of igneous rocks was discussed, and the variation law of grouting parameters and grouting effect were analyzed, which could provide reference for future similar projects.
