Abstract
The invention discloses a reconstruction method for a water-proof shell. The distribution condition of aquifers around an ore body is determined; reconstruction of the water-proof shell is performed in the aquifers; and a complete continuous water-proof key layer is formed around the ore body. The required thickness of a water-proof top plate is calculated in combination with an actual engineering condition and a mechanical principle. Whether damage occurs is judged by simulating water-proof shell stress, plastic zone and settlement distribution condition by utilizing Flac3d under an ore body mining condition. In engineering implementation, detection holes are firstly formed in the aquifers and positions of karst caves and fissures are determined by using a geological survey instrument, connection roadways are constructed in the aquifers around a middle section, and drilling and grouting underground chambers are constructed on parts of the roadway close to the fissures of the aquifers. Grouting holes are rationally arranged in the roadways and the underground chambers and encrypted grouting is performed, and finally, inter-hole CT (Computed Tomography) fluoroscopy is performed to check the grouting and water plugging effect. According to the method, a mine floor mining environment is reconstructed, so that mine floor mining is performed safely and efficiently, and geological disasters are effectively reduced.
Description
Technical field
The present invention relates to the water proof shell reconstruction method in a kind of mine safety field.
Background technology
For flood karst orebody mining, take the effective underground water scheme of preventing and treating to seem and be even more important.Traditional sewer drainage is the main anti-scheme of harnessing the river, because in recovery process, drainage a large amount of underground water, so that the groundwater in mining area position descends, form large-scale cone of depression, cause easily surface subsidence, form a series of geological disaster, not only increase the mine drainage burden, cause the mineral deposit high-efficiency and continuous to exploit, and cause easily workers and peasants' contradiction.As still taking to reserve the Hu Ding ore deposit, with anti-the harness the river scheme of 10m * 10m net degree to moisture top board construction Using Horizontal Bridgman Method to injected hole, then not only waste a large amount of mineral resources (ore deposit of extraction amount only account for residue ore deposit amount about 1/3rd), and have the threat of water inrush and inundate mine.If only in the top board aquifer, carry out water proof key stratum grouting and reinforcing, ignore the karst declogging situation of side direction rock mass or floor rock, the mine production safety still can't be protected.Therefore, how carrying out safety, high-efficiency mining and don't cause degradation geological disaster under surface subsidence, the groundwater table, is the large problem that flood karst orebody mining need to face.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can safety, high-efficiency mining and don't cause the water proof shell reconstruction method of surface subsidence, groundwater table decline geological disaster.
