以肖家洼煤矿211304材料顺槽与上部的迎采综放工作面211303工作面为工程背景,在弄清211304材料顺槽巷道破坏机理和控制机理的基础上,分析迎采对掘动压巷道破坏机理,研究巷道围岩应力、围岩变形、支护强度三者间的协调关系,提出合理的采动影响下的巷道围岩控制技术,对工作面正常推进,降低巷道维护工程量和成本,提高经济效益,保证矿井安全高效生产具有重要意义。
Abstract:Based on the engineering background of 211304 material tunnel and 211303 working face of top face mining in xiaojiawa coal mine, on the basis of clarifying the failure mechanism and control mechanism of 211304 material tunnel, analyzes the failure mechanism of face mining to driving dynamic pressure tunnel, studies the coordination relationship among stress, deformation and support strength of surrounding rock, and puts forward reasonable surrounding rock under the influence of mining, the control technology is of great significance to the normal advancement of the working face,the reduction of the quantity and cost of roadway maintenance, the improvement of economic benefits and the guarantee of the safe and efficient production of the mine.
