提出了一种针对矿井施工的注浆堵水工程方案,从布置注浆孔、选取注浆深度、材料、段高与方式3方面出发治理漏水问题,在施工过程中注意钻孔偏斜与纠正问题,针对岩层裂隙阻力小、吸浆量大等问题采取积极解决措施。提出了注浆堵水新技术,利用ZGS-1型水力膨胀式单管止浆塞、DSC-1型冻结壁声波测厚仪、黏土水泥浆液来提高抗渗性,为矿井施工提供安全、良好的环境。
A project of grouting and water blocking for mine construction was put forward. From the aspects of grouting holes, selecting the depth of grouting, material, section height and mode 3, the leaking problems should be controlled. During the construction, pay attention to the deviation and correction of borehole Problem, in view of the rock fissure resistance is small, large amount of suction and other issues to take positive measures to solve. Proposed a new technology of grouting water plugging, using ZGS-1 hydraulic expansion single grouting plug, DSC-1 frozen wall sonic thickness gauge, clay cement slurry to improve the impermeability for mine construction to provide a safe, good environment of.
