Problems solved by technology

Although these anti-seepage methods can achieve a certain anti-seepage effect, they have their own advantages and disadvantages. They only consider the anti-seepage performance of the method itself, and seldom consider the stress of the material itself and the corrosion protection of the material. Therefore, when In the case of cracks caused by tension at the bottom of the river bed, the anti-seepage effect of the above method is not good, and the treatment cost is high

Embodiment Construction

[0022] A certain mining area is currently starting to mine the 3229 working face. After mining, the disturbed strata and surface subsidence will affect the Jinsha River Basin, and the subsequent mining of the working face will be carried out under the Jinsha River and nearby areas. Due to the thin Quaternary strata in this area, most strata are dominated by bedrock. The water-conducting fissure zone formed by the mining of the working face and the cracks at the edge of the surface subsidence area will lead to the backflow of Jinsha River water into the underground, posing a serious threat to the production and safety of the working face. Therefore, the quaternary structure is used to control the seepage of the Jinsha River.

[0023] The anti-seepage structure is divided into four layers from bottom to top, which are: river bed reinforcement layer, anti-seepage cushion layer, anti-seepage layer, and anti-seepage protective layer. Combine below figure 1 ~4 the present invention...

Abstract

The invention belongs to the field of mines, and relates to a riverbed seepage-proof governing structure. According to the riverbed seepage-proof governing structure, a quaternary seepage-proof structure is arranged on a disturbed riverbed, and the quaternary seepage-proof structure is divided into four layers from bottom to top, namely a riverbed reinforcing layer, a seepage-proof cushion layer, a seepage-proof layer and a seepage-proof protective layer are sequentially laid. According to the design, engineering geology, environment characteristics and technical features of a composite geo-membrane are fully considered, and therefore the effect of the disturbed riverbed seepage-proof governing is enabled to good, and governing cost is lower.

Description

technical field [0001] The invention belongs to the field of mines, and relates to a river bed anti-seepage control method, in particular to a four-element anti-seepage method and structure for disturbing the river bed after mining. [0002] Background technique [0003] When the "three-down" mining is to be carried out, the impact range of the stratum and surface subsidence disturbed by the mining will spread to the river basin, and the water-conducting fissure zone and surface subsidence formed by the mining of the working face will cause the river water to flow back into the underground, causing serious damage to the working face. Production and safety pose a serious threat, so it is necessary to carry out anti-seepage treatment works on the disturbed riverbed. At present, the main anti-seepage measures for rivers are artificial canal anti-seepage, anti-seepage membrane, grouting anti-seepage, new information anti-seepage, curtain grouting, masonry anti-seepage, asphalt ...
