摘要
Abstract
Through calculation and analysis, the overlying strata failure form and height of 1 and 3 coal seam in the theory is concluded, then by means of laboratory similar material simulation study, simulated the development height of the water- flowing fractured zone, combined with the field measured data, summarizes the immediate roof weighting step distance, roof first weighting step distance,and the old roof periodic weighting step distance of Ding Jia Cheng coal mine during working face mining, The feasibility of ascending mining of the 1 coal and 3 coal mining is was analyzed.关键词
