Embodiment 1
[0035] The utility model relates to an anti-seepage structure suitable for sealing up mountain fissures with mine caves inside.
[0036] refer to figure 1 The anti-seepage structure includes a support layer 1, a hydrophobic material waterproof layer 2, a coarse sand water-guiding and drainage layer 3, and a covering soil layer 4, which are sequentially arranged from the lower end of the mountain fissure, wherein: the filling material of the support layer 1 includes cement, A mixed filler made of bentonite and sulfonated lignite in a certain proportion; the hydrophobic material waterproof layer 2 is composed of granular hydrophobic particles with uniform particle size; the covering soil layer 4 includes a soil layer and a plant layer.
[0037] Further, the mixed filler is prepared by mixing cement, bentonite and sulfonated lignite at a ratio of 5:1:0.5, and then the mixed filler and water are mixed at a ratio of 1:1 and then injected into the cracks of the mountain body to form...
Embodiment 2
[0041] This embodiment provides a kind of anti-seepage method suitable for the plugging of mountain fissures with mine caves inside. This anti-seepage method is based on the anti-seepage structure in embodiment 1. Refer to figure 2 , which specifically includes the following steps:
[0042] Step 1: Use geophysical prospecting methods to investigate the development of fissures in the mountain where the mine is located, and finally determine the location of each fissure or gap and its impact on water seepage in the mine;
[0043] Step 2: For the identified cracks or gaps, use manual or engineering machinery equipment to clean up the surface soil and expose it;
[0044] Step 3: Prepare cement, bentonite and sulfonated lignite in a ratio of 5:1:0.5 to make a mixed filler, and then mix the mixed filler and water in a ratio of 1:1 to make pulp;
[0045] Step 4: Inject the mud prepared in Step 3 into the cracks in the mountain body with an injection pump. Under the action of gravit...
Embodiment 3
[0050] In order to control the weathering and leaching of ore from the source and reduce the amount of mine wastewater, this embodiment adopts the idea of water stop outside the mine to reduce the infiltration of rainwater at the source, and provides a suitable method for sealing cracks in mountains with mines inside. Anti-seepage method to solve the pollution problem caused by mine discharge wastewater.
[0051] This method specifically includes:
[0052] Step 1: Use the high-density electrical resistance method and the borehole imaging method to detect the distribution of cracks around the mountain where the mine cave is located;
[0053] Step 2: For non-water-filled fissures, use excavators and other equipment to clean the surface soil of the fissures, and for water-filled fissures, use pumping and clearing to outline relatively obvious fissures;
[0054] Step 3: Prepare cement, bentonite and sulfonated lignite in a ratio of 5:1:0.5 to make a mixed filler, and mix the mi...
