Automatically controlled full-mechanized caving mining loose visual simulation experiment table

Abstract

The invention provides an automatically controlled full-mechanized caving mining loose visual simulation experiment table. The invention comprises a experiment table framework, a visual portion, a remote control apparatus, a top coal support grid and moving system, a support moving system and an angle adjusting system; The main body of the experiment table employs a frame-type structure, and the side surface of the experiment table framework employs a transparent plastic plate, and the remote control apparatus controls the simulation experiment table system, and experiment table system control parameters are set by the remote control apparatus, and an initial goaf is simulated on the experiment table frame, and a spoil baffle plate is disposed behind the initial goaf, thereby the simulation is directly in a normal top coal case; the top coal support grid is temporarily supported by top coal and the top board, and the support employs a simple top coal support, and support is provided with a gear which moves on a self-moving track, and the support gear is driven by a stepping motor, and a tooth bar which is engaged with the support gear is fixed on a experiment table framework base plate, and the top coal support grid moves on the self-moving rack by the support which is remotely controlled by a stepping motor.

Description

technical field [0001] The invention is a bulk visual simulation test platform for controlled fully mechanized caving mining, which realizes the visual simulation and automatic control of the flow characteristics of fully mechanized caving mining coal gangue and the law of mixing gangue, and can simulate different mining conditions at the same time to explore different mining conditions. The influence of coal technology on top-coal recovery during fully mechanized caving provides an experimental basis for the determination of reasonable process parameters for automatic top-coal caving. Therefore, according to the geological and technical conditions of the large mining height fully mechanized caving face, it is an urgent need to study the characteristics of the coal gangue flow field of the large mining height fully mechanized caving face, and optimize its process parameters on this basis to achieve safe and efficient mining of the working face. solved problem.
