A coal mine underground sluice wall water retaining simulation test system and method

Abstract

The invention discloses a water retaining simulation test system for an underground water gate wall of a coal mine and a method. The system comprises a water supply and pressurizing system, a water gate wall water retaining surrounding rock permeation device, a surrounding rock load device, a flow test system, a data acquisition system, a data storage system and a power supply system. The method comprises steps including proportioning and preparation, laying and embedding of sensors, material consolidation and application of a surrounding rock compensating load, water gate wall water retaining simulation, data acquisition, flow monitoring, data processing and water gate wall water retaining law analysis. Problems that water gate walls of coal mines have large difficulty in underground construction and are difficult to observe and reconstruct after running and the like can be solved, the working state of the underground water gate wall of the coal mine is reproduced through a simulation test, the change law after water retaining by deep surrounding rock is disclosed, problems about states of the water gate wall under different working conditions are easy to find, a scientific basis is provided for optimization and adjustment of the design scheme of the water gate wall, the system has the great practical significance in guaranteeing of safe coal mining and has the significant popularization and application value for coal mines having corresponding mine water prevention projects.

Description

technical field [0001] The invention relates to the technical field of parameter collection and monitoring of a sluice wall water prevention project in a coal mine, in particular to a sluice wall water retaining simulation device. Background technique [0002] Coal mining in my country has a long history, and the hydrogeological conditions of coal fields are complex and changeable. Mine water damage constitutes one of the main disasters in my country's coal mines. Minor mine flood accidents wash away the working face, submerge equipment, and increase the burden of mine drainage. Severe cases cause casualties, well flooding, resulting in major economic losses and seriously threatening the lives of miners. At present, there are many mature mine water prevention and control methods in my country. As an engineering measure, sluice walls have been widely used, especially in flood mines with complex hydrogeological conditions and serious flood threats. Waterlogging, water-filled k...
