Waterproof curtain gap plugging device and process based on microbial mineralization
The invention discloses a waterproof curtain gap plugging device and process based on microbial mineralization, and belongs to the technical field of mine water control, the waterproof curtain gap plugging device comprises a cementing liquid pool and a bacterial liquid pool, and the cementing liquid pool and the bacterial liquid pool are both communicated with a multi-channel peristaltic pump through pipelines. According to the method, mineral substances are induced to precipitate cementation particles through the microbe induced calcium carbonate precipitation technology and the mineralization effect in the microbe metabolism process, the technology is applied to waterproof curtain crack plugging, the curtain water plugging capacity can be effectively improved, and the slurry is the microbe suspension liquid and the uric acid and calcium chloride solution; compared with cement and chemical pulp, the slurry is low in viscosity, good in fluidity, strong in permeability and large in diffusion radius, the microbial suspension, the uric acid and the calcium chloride solution are all environment-friendly substances, the microbial mineralization effect is also a common biological induction mineralization reaction process in the nature, and the whole slurry is more environmentally friendly.
本发明公开了一种基于微生物矿化作用的止水帷幕缝隙封堵装置及工艺，属于矿井水防治技术领域，包括胶结液池和菌液池，所述胶结液池和菌液池均通过管路连通有多通道蠕动泵。本发明中，通过微生物诱导碳酸钙沉淀技术，利用微生物新陈代谢过程中的矿化作用进行诱导矿物质沉淀胶结颗粒，该技术应用于止水帷幕裂隙封堵，可以有效地提高帷幕堵水的能力，并且浆液为微生物悬浮液和尿酸及氯化钙溶液，相比水泥和化学浆，浆液粘度低、流动性好、渗透性强，扩散半径大，其中，微生物悬浮液和尿酸及氯化钙溶液均是环境友好型的物质，微生物矿化作用也是自然界中常见的生物诱导矿化反应过程，整体上更加绿色环保。
