Strip mine water-rich deep hole isolation slurry material and preparation method thereof
The invention discloses a strip mine water-rich deep hole isolation slurry material and a preparation method thereof. The strip mine water-rich deep hole isolation slurry material comprises the following components in parts by weight: 50 parts of fly ash, 50 parts of clay, 37-38 parts of water, 3 parts of a foaming agent, 2.5-3 parts of an accelerator, 2 parts of an early strength agent and 2-3 parts of a thickener.. The fly ash, the clay, the accelerator, the early strength agent and the thicker are mixed and stirred for 3-5 min in a dry state; the method also includes adding a foaming agentinto water, and fully and quickly stirring for 3-5 minutes; adding the obtained mixture into the mixed solution, stirring for 1-2 minutes, doping bubbles as much as possible, and standing for 20 minutes. The density of the material is slightly greater than that of water, is close to that of sensitized emulsion explosives, is immiscible with the sensitized emulsion explosives, has certain dispersion resistance underwater, and is relatively low in viscosity and relatively good in flowability. The problem of water-rich deep hole explosive isolation can be effectively solved, the emulsion explosive consumption is reduced, the operation is simple and convenient, the isolation material consumption can be flexibly adjusted according to the field condition, and different isolation distances are further realized. Quantitative isolation of blasting explosives in the water holes and drainage of accumulated water in the holes can be finally realized through pipeline injection.
本发明公开了一种露天矿富水深孔隔离浆状材料及其制备方法，其原料按重量分数计包括粉煤灰：粘土：水：发泡剂：速凝剂：早强剂：增稠剂＝50：50：37‑38：3：2.5‑3：2：2‑3。将粉煤灰、粘土、速凝剂、早强剂、增稠剂干态下混合搅拌3‑5min；将发泡剂加入水中并充分快速搅拌3‑5min；将所得的混合物加入混合液中，搅拌1‑2min，同时尽可能多地掺入气泡，静置20min。该材料密度略大于水，与敏化后的乳化炸药密度接近且不相溶，且在水下具备一定抗分散能力，粘度较低，流动性较好。可以有效解决富水深孔炸药隔离问题，节省乳化炸药用量，操作简便，并且可以根据现场情况灵活调整隔离材料用量，进而实现不同的隔离距离。可以通过管道注入，最终实现在水孔中定量隔离爆破炸药并排出孔内积水。
