Discussion on the related issues of average mining depth in coal mining subsidence

Zhang Xinying;Wang Yuzhen;Department of Civil Engineering,Henan Vocational College of Water Conservancy and Environment;  
In the measured data processing of mining subsidence,the average mining depth is often adopted instead of the actual mining depth of the main section along strike.Aiming at the situation,the author solved respectively the mining depth offset coefficients in three different conditions,and classified them again.Then the relationship between the mining depth offset coefficient and the overlying strata lithology or coal seam dip angle was discussed,and the effects of the mining depth offset coefficient on relative parameters were deduced.The results showed that the mining degree had no influence on the coefficient,but the overlying strata strength,the coal seam dip angle had positive correlation with the coefficient.The bigger the coefficient was,the larger the difference value between computational main influence radius and the actual was.
