摘要
针对目前薄煤层沿空留巷特点,结合某矿具体条件,研究了一套包括膏体材料组分及配比、充填工艺、巷旁支护、巷内支护在内的一整套薄煤层沿空留巷技术,并运用数值模拟方法对巷旁充填体宽度进行了进一步研究,在该矿取得了较好的经济技术效果。研究结论对于类似条件下的薄煤层开采具有一定的参考价值。
Based on condition of a mine,a whole set of technology of retaining roadway along gob including paste material component,proportioning,stowing technique,roadway and roadway-side supporting was developed.Numerical simulation was applied to obtaining width of stowing body.This technology made good economical and technical effect.Results might provide reference for thin coal-seam mining with similar condition.
