Study On Mining Technology Of Fully Mechanized Mining Working Face Of Steeply Dipping Seam In Babao Mine

Coal is the main energy in China. The future for quite a long time, although the coalproduction and consumption may be decreased, but the dominant position will notchange. With the development of economy, the coal mining intensity increasesceaselessly, many mines had to be in relatively good condition of coal seam mining tocoal seam under complicated.The coal mining technology of Complicated difficultmining coal seamis one of the main problems which restrict the high yield and highefficiency of coal mines in our country. The1101mining area is taken as theengineering background. The theoretical analysis, laboratory test, field test, numericalsimulation and other methods and means are adopted. According to the geologicalconditions of1101mining area, using,"the complexity analysis and application of coalseam mining method selection software system", the suiTab. mining method of1101mining area are analyzed, the analysis result is in accordance with the selected miningmethod. A detailed analysis of the working surface of broken coal wall and the roofstability influencing factors, puts forward the broken roof and coal wall of preventionmeasures, and design of chemical grouting reinforcement scheme. Determination ofworking face in physics and mechanics parameters of surrounding rock based on RFPAsimulation, using the working face roof rock activity law and the law of mine pressurebehavior, for guiding the actual construction, provide the basis for. Using FLACsoftware to analyze the grouting rock bolt supporting effect, and in the underground coalwall and roof of chemical grouting reinforcement test, optimization and programme, asBabao mine safety, high-efficiency mining to provide protection.
