Problems solved by technology

[0003] Due to the concealment of underground mining engineering, it is difficult to study the mechanism of water and sand migration and inrush in overlying rock fractures caused by coal mining with the help of on-site observation. Laboratory experiments have become an effective means to solve this problem. However, in the current During the water-sand inrush test, the test chamber cannot be stably fixed and shakes, and the height of the water chamber cannot be adjusted according to the demand. When used in different situations, the angle of the water-sand separation and metering equipment cannot be adjusted. Thus affecting the test results, for this reason, we propose a water-sand inrush test system and monitoring method to solve the above problems

Abstract

The invention discloses a water and sand surge test system. The water and sand surge test system comprises a fixed box; a placement box is fixed at one side of the fixed box; a rotary module is arranged in the fixed box; four first screws are arranged on the rotary module; furthermore, one ends of the four first screws are rotatably connected to the bottom in the fixed box; one ends of the four first screws pass through the side wall of the fixed box, and extend to the upper end of the fixed box; the upper ends of the four first screws are used for fixing a beam together; an oil cylinder is fixed on the beam; and the piston rod of the oil cylinder passes through the beam, and extends to the lower end of the beam. The invention further discloses a water and sand surge test monitoring method. By means of the water and sand surge test system and monitoring method in the invention, the problem that a test chamber cannot be stably fixed is solved; simultaneously, the problems that a water and sand separation and metering device is poor in stability and angle adjustment cannot be carried out are also solved; the system can be adjusted at any time according to requirements; the flexibility is high; therefore, the test data accuracy rate is increased; and the system is simple to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of water-sand inrush, in particular to a water-sand inrush test system and a monitoring method. Background technique [0002] At present, coal in the western region has the characteristics of large thickness, shallow buried depth, thin bedrock, and thick loose sand layer overlying it. The overlying rock movement induced by the mining of this kind of coal seam is strong and has a wide range, and it is difficult for the overlying rock to form a relatively stable support structure. The water-sand mixture with good water quality and high sand content collapses into the underground working face along the cracks in the mining overlying rock, resulting in frequent accidents that cause property losses and even casualties, posing a great threat to the safe production of mines. To ensure the steady development of coal resources and get rid of the serious problem of water and sand inrush disasters, when mining coal un...
