Abstract
According to the actual situation of 43115 iace cuncaota mitre,we use the numerical calculation software to conduct a simulationg study with surrounding rock deforation and stcss condition of roadway on the different coal pillar width, using numerical calculation software in order to make a Rea- sonable suggestion of Coal pillar's width for 43115 face cuncaota mine. Based on field observation of support pressure distribution law in different coal pil- lar width, with the application of elastic nuclear theory, we get the conclusion of practical coal pillar width. Finally, we obtain the reasonable width of coal pillar.关键词
