Abstract

A coal mine mining working face roof water regimen real-time dynamic monitoring test device disclosed by the invention comprises a frame body and a base, a first motor is fixed on the inner wall of the base, the driving end of the first motor is fixedly connected with the outer wall of the frame body, a clamping mechanism is arranged between the frame body and the base, a bottom plate is fixed in the frame body, a rock mass is fixed to the upper side wall of the bottom plate, a stress contact located on the lower side of the rock mass is further fixedly embedded in the upper side wall of the bottom plate, a second motor is fixed to the inner wall of the frame body, and a two-way lead screw is horizontally arranged and fixed to the driving end of the second motor. The device has the advantages that the rock mass and the bottom plate which are made of the same material of a coal mine are arranged, the water tank is in contact with the bottom plate, material losses of the rock mass and the bottom plate in the drilling process under different water body thicknesses are simulated, stress monitoring is conducted through the stress contact, and monitoring of the loss ratio and stress changes of the rock mass under the different water body thicknesses is achieved.

Description

technical field [0001] The invention relates to the technical field of coal mine mining monitoring tests, in particular to a real-time dynamic monitoring test device for roof water conditions in coal mine mining working faces. Background technique [0002] At present, with the continuous deepening of coal seam mining, the geological structure and hydrogeology are becoming more and more complex, and the depth of damage to the floor caused by mine pressure and mining stress is increasing. Mining water inrush has increasingly become a major threat to mine water hazards. [0003] At present, the research on the roof and bottom water regime mainly includes on-site detection method and indoor simulation method, but the actual dynamic monitoring of the impact on the roof under different water regimes on the bottom plate cannot be carried out, so the significance of actual dynamic monitoring has been lost. [0004] In order to solve the above problems, we proposed a real-time dynam...
