Problems solved by technology

However, this method is a theoretical prediction of the development height of the water-conducting fracture zone, and can only obtain a single height value of the water-conducting fracture zone, which lacks practical verification, and cannot determine the specific development form of the water-conducting fracture zone

Abstract

The invention discloses an underground detection method for the development form of a roof water-guiding crack zone, and belongs to the field of underground water environment monitoring, and the method comprises the following steps: 1, predicting the development height of a caving zone and the maximum development height of the water-guiding crack zone; 2, assuming that the development form of thewater guide fracture zone is saddle-shaped, arch-shaped or saddle-arch-shaped, and drawing predicted different development forms of the water guide fracture zone; 3, designing a specific underground detection scheme of the development form of the water guide fracture zone according to the development form of the water guide fracture zone; 4, carrying out underground actual measurement by adoptinga borehole leakage detection method; and 5, analyzing the development positions of the K2, K3 and K4 hole water guide crack zones on the detection profile, and determining the development form of theroof water guide crack zones according to three conditions. The method is simple in step, and the development form of the roof water guide crack zone is accurately determined to be saddle-shaped, arch-shaped or saddle-arch-shaped. The maximum development height of the water guide crack zone can be detected while the water guide crack zone is arched, the shape of the caving zone is determined, monitoring of the underground water environment is facilitated, and the ecological environment is protected.

Description

technical field [0001] The invention relates to the technical field of groundwater environment monitoring, in particular to an underground detection method for the development form of roof water-conducting fracture zones. Background technique [0002] In recent years, the focus of my country's coal resource mining has shifted from the eastern region to the northwestern region. The annual precipitation in the northwestern region is less than 200mm, which belongs to the arid and semi-arid climate. Water resources are scarce and the ecological environment is fragile. It causes serious leakage of shallow groundwater, the groundwater level drops, the water volume of surface reservoirs and rivers decreases or even dries up, vegetation withers, and the ecological environment is seriously degraded. In order to protect the ecological environment and maintain the sustainable development of the regional economy, domestic scholars have put forward the viewpoint of "water conservation coa...
