我队在毛菇坝施工的地层，构造复杂，节理裂隙发育，岩层破碎，大多数钻孔都漏水、坍塌，而且有一些钻孔不仅又漏又塌，还出现又漏又涌，用泥巴、稻草、马粪、纤维物、石灰乳泥浆、下水泥等堵漏方法，收效很小。经过近几年的摸索，用冻胶泥浆堵漏，是适合该地区的一种较好的堵漏方法。冻胶泥浆是以水玻璃、普通泥浆和水泥三者按照一定的比例混合后所形成的一种半固体状态的物质。它触变性很大，流入漏层后能很快形成结构，凝成冻胶，并能承受一定的液柱压力，以阻止冲洗液流失。鉴于冻胶泥浆的这一特性，我们曾首先在兴隆矿区ZK20—1溶洞裂隙发育的大理岩中，进行了堵漏试验。开始，这次由于材料的混合比和待凝时间没有掌 The construction of the team in the mushroom dam formation, complex structure, fractured joints, rock crushing, most of the drilling leaks, collapsed, and some holes not only leak again collapsed, but also leak and Chung, with mud, Straw, horse manure, fiber, lime milk mud, cement and other plugging methods, with little success. After several years of exploration, the use of gel glue plugging, is suitable for the region a better method of plugging. Jelly glue is a semi-solid material formed by the mixture of water glass, ordinary mud and cement according to certain proportion. It is thixotropic, into the leakage layer can quickly form a structure, gel into jelly, and can withstand a certain liquid column pressure to prevent the loss of flushing fluid. In view of the characteristics of frozen gel, we first conducted a plugging test in the marble developed in ZK20-1 karst caves in Xinglong Mine. Beginning, this time due to the mixing ratio of materials and to be coagulated time without palm
