Embodiment Construction
[0024] The present invention provides an experimental device and experimental method for measuring the dust production law of coal mine fully mechanized caving face. In order to make the purpose, technical scheme and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0025] The invention provides an experimental device for measuring the dust production law of fully mechanized caving working faces in coal mines, such as figure 1 , figure 2 and image 3 As shown, it includes a cover body 8 made of glass for simulating the fully mechanized caving face, wherein a coal setting platform 1 is arranged on one side of the cover body 8, and a second A transmission belt 2, a simulated shearer 3 is set on one side of the coal setting area of the coal setting platfor...

The invention discloses an experimental device and an experimental method for measuring the dust production law of fully mechanized caving working faces in coal mines. A coal setting platform is arranged on one side of the cover body, and a first transmission belt is arranged below the coal setting area of the coal setting platform. A simulated shearer is set on one side of the coal setting area of the coal setting platform. The cutting head of the simulated shearer corresponds to the coal setting area. A hydraulic support is set on one side of the simulated shearer, and a hydraulic support is set above the hydraulic support. A coal collection box, with broken coal blocks arranged in the coal collection box, a second stress applying device arranged above the broken coal blocks, and a second transmission belt arranged below the tail beam of the hydraulic support. It has the advantages of simple structure, reasonable layout, convenient detection, etc. It can simulate the shearer's cutting of coal blocks without stress, downwind or upwind coal cutting, and coal cutting at different speeds of the cutting head. The dust production status of the upper coal block without stress, moving and coal discharge work, and has the function of timely recording and synchronous data processing.
Description
technical field [0001] The invention relates to a simulation experiment device and method, in particular to an experiment device and an experiment method for measuring the dust production law of fully mechanized caving working faces in coal mines. Background technique [0002] At present, the vast majority of coal mines in my country are underground mining, and coal mines are developing towards large-scale and automatic development. However, with the continuous improvement of the mechanization degree of coal mining, the dust production in the mine working face has increased. As we all know, the coal mining face is one of the most important sources of dust production in the mine. The cutting of the coal mining machine and the movement of the hydraulic support will generate a lot of dust, and the fully mechanized caving face has become a dust-producing One of the most coal face ways. High-concentration dust that seriously exceeds the standard will not only seriously threaten...
