Abstract

The invention provides a dust migration simulation test system for a fully mechanized mining face and a working method thereof; the blank in the prior art is filled, and restrictions caused by objective factors such as manpower, material resources, economy, condition control and safety in the full-size mine fully-mechanized coal mining face dust migration experiment process are avoided. The simulation test system comprises an experiment simulation main body platform, an image monitoring assembly is arranged above the experiment simulation main body platform, an environment monitoring assembly is arranged in the experiment simulation main body platform, and a dip angle adjusting assembly is arranged on the lower portion of the experiment simulation main body platform. The experiment simulation main body platform is respectively connected with the dust release adjusting assembly, the spraying and dust falling assembly and the dust flow control assembly; and the image monitoring assembly, the environment monitoring assembly, the dust release adjusting assembly, the spraying and dust falling assembly and the dust flow control assembly are all connected with an upper computer. The device can simulate the dust migration rule of the fully mechanized coal mining face, and has the advantages of good operability, reproducibility and the like.

Description

technical field [0001] The invention relates to the technical field of mine ventilation and dust reduction experiments, in particular to a fully mechanized mining flour dust migration simulation test system and a working method thereof. Background technique [0002] The fully mechanized mining face is one of the workplaces where mine production equipment is concentrated and personnel work intensive. In recent years, with the heavy-duty and large-scale of fully-mechanized mining equipment, the dust output and dust concentration of fully-mechanized mining work have increased significantly, seriously polluting the underground working environment, reducing the service life of equipment, and causing the number of people suffering from pneumoconiosis in coal mines to increase year by year . According to the National Health and Family Planning Commission, pneumoconiosis is the largest occupational disease in my country. In 2012, 24,206 cases of pneumoconiosis were reported nationw...
