Analysis of Close Distance Coal Seam’s Mining Rational Staggered Distance

Abstract:

As 2# and 3# coal in Baoxin coal mine are close distance coal seams, combined mining is adopted to ensure the production, and reasonable staggered distance needs to be determined between the upper and lower adjacent workfaces. Calculated on the influence of strata movement, there is a empirical formula for the coal’s alternate distance.It is necessary to analyze the factors in the formula
