Theme Project of National 863 Plan of the 12th Five-year Plan

Key Techniques and Equipment for Mining of Thin Coal Seams

Project number: 2012AA062100, Chief Expert: Tu Shihao

Brief Introduction of the Project

On the basis of classifying the mining techniques of major coal mines in the middle and eastern areas, this project focuses on establishing mechanized mining technique system for thin coal seams, developing drill-type mining machines and small cross-section semi-coal heading machinesfor ultra-thin coal seams, researching and developing the collection, transmission, monitoring device and system of mining face space environment information as well as mining equipment information, intelligent operation of coal mining machines, automatic adjustment of holdersperformance, automatic movement of holders and scraper conveyers, and “three-machine linkage control system, developingsafety mining guarantee techniques, like prevention and control of fully-mechanized mining face gas, roof, dust, etc, so as to conquer key generic techniques that influence efficient mechanized mining, promote the intellectualization development of our country’s mining technology, and provide technical support for the sustainable development of the coal industry.
