Problems solved by technology

However, in order to ensure the tightness of the system, filter elements are added to the top and bottom of the rock sample to prevent the outflow of particles, so it cannot be directly used to study the seepage law when the broken rock changes quality.

Abstract

The invention provides a permeation device for water and sand two-phase seepage of a fractured rock mass. The permeation device comprises a longitudinal loading mechanism, a supporting frame, a permeation device body and a pressure control device, wherein the permeation device body comprises the supporting frame, and a permeameter and a longitudinal loading mechanism which are mounted on a pedestal of the supporting frame; the longitudinal loading mechanism is mounted at the upper end in the supporting frame through a bolt; the permeameter is arranged at the lower end in the supporting frame; the permeameter comprises a cylinder base, a filter device, a gravel cavity and a water and sand cavity. The permeation device for water and sand two-phase seepage of the fractured rock mass has the advantages of stable and continuous supplying of a dynamic pressure water source, openness of sand grain loss, sand grain collection and the like; all performance indexes of a permeation system are matched, and the stability is high; an experiment can be repeatedly tested, and real and accurate test data can be guaranteed; the permeation device has certain reference significance.

Description

technical field [0001] The invention relates to the technical field of osmosis, in particular to an osmosis device for breaking rock mass water-sand two-phase seepage. Background technique [0002] In the process of high-intensity mining in the western mining area, disasters such as roof cut and frame collapse, water inrush and sand collapse are extremely prone to occur. In the Shendong mining area alone, Daliuta Coal Mine had three serious accidents of large-scale roof cut and frame collapse in the working face. Seriously affected the safe and efficient mining of mines, resulting in direct economic losses of more than 60 million yuan. Due to shallow water and quicksand entering the mine during roof damage, there were four serious roof water and sand inrush disasters in the Shendong mining area in 2011. Among them, the roof water and sand inrush occurred in Buertai Coal Mine in November 2011. 60 supports on the working face were buried, and a subsidence pit with a diameter ...
