Experiment for simulating whole process of fully-mechanized coal mining of underground coal mining roadway and teaching system thereof

Abstract

The invention belongs to the fields of underground coal mine omnidirectional simulation and teaching, and particularly relates to an experiment for simulating a whole process of fully-mechanized coalmining of underground coal mining roadway and a teaching system thereof, which solve the problem that the experiment and the teaching system covering the whole process of coal mining is lacking in China. The system comprises a fully enclosed glass steel house and a simulated roadway arranged in the fully enclosed glass steel house, a hydraulic support, an electric traction coal cutter, a scraper conveyor, an artificial coal walls and an independently installed fully enclosed coal seam liquefaction experiment apparatus and a fully enclosed coalbed gas pumping experimental device. The system caneffectively guarantee the safety of the experimental training of the students, and saves a lot of internship funds, the students can personally carry out the operation of the fully mechanized miningequipment, and teachers can conduct research on various projects and effectively cultivate talents combining theory and practice.

Description

Technical field [0001] The invention belongs to the field of omnidirectional simulation and teaching in underground coal mines, and specifically relates to an experiment and teaching system for simulating the whole process of fully mechanized mining of underground coal mining roadways. Background technique [0002] At present, all foreign coal mining equipment manufacturers only have the equipment factory parameter test, and they have not tested the equipment on the artificial artificial coal wall. In China, only China Coal Zhangjiakou Coal Machinery Co., Ltd. has built a fake coal wall. The project mainly studies scraper conveyors. The overall performance index of the coal mining machine, there is little research on the coal mining machine and the support; due to the high cutting cost of the coal mining machine, it cannot meet the requirements of the students' production training; Zhangjiakou is a professional manufacturer of scrapers, and has not yet sprayed the coal mining mach...

AI Technical Summary

Problems solved by technology

[0002] At present, foreign coal mining equipment manufacturers only test the factory parameters of the equipment, and do not test the equipment on the simulated artificial coal wall. In China, only China Coal Zhangjiakou Coal Machinery Co., Ltd. has built a fake coal wall. This project mainly studies the scraper conveyor There is little research on the shearer and the support; due to the high cutting cost of the shearer, it cannot meet the requirements of students' production training; Zhangjiakou is a professional manufacturer of scraper machines, and there is no spray on the shearer. Dust removal and cooling system should be studied; as the core equipment of the working face, the coal shearer cannot carry out quantitative structural force analysis and reliability analysis; Carry out safety ventilation monitoring and monitoring; without pre-buried pipelines and bedding structures, it is impossible to conduct research on gas and water extraction methods; in addition, the driving mode, structure and mechanism of the shearer, safety production, coal compression and coal mining There is a lack of research on green mining, etc.; there is no closed coal seam, and the gasification of underground coal seams cannot be studied
