Exploration of Excavation Support Technology of Coal Mining Under Complex Geological Conditions
Coal is currently the main source of energy in China,and the importance of its mining safety and effi-ciency is increasing day by day.However,complex geological conditions such as unstable rock formation,densely faulted area and high ground stress environment,have brought many troubles to coal mining.The use of advanced excavation support technology has become a powerful support to ensure the safety of mining operations.The paper introduces several kinds of coal mining excavation support technology under complex geological conditions,and then puts forward the key points of support technology such as reasonable selection of excavation support equip-ment,construction process control and implementation of safety measures,in order to improve the effectiveness of support technology in solving complex geological problems in coal mines.
