Analysis of filling effect and filling ratio of backfill mining in longwall face
長壁工作面充填開采的充填比與充填效應(yīng)分析
Based on full literature search and comprehensive analysis,the current status is described from the mining technologies of coordinated mining,backfill mining,partial strip mining,and filling the collapsed cavities in over lying strata.
在綜合分析大量文獻(xiàn)的基礎(chǔ)上,從協(xié)調(diào)開采法、充填開采方法、條帶開采、覆巖離層注漿等多種開采技術(shù)對建筑物下開采方法進(jìn)行了研究和論述;展望了我國建筑物下開采的發(fā)展趨勢,認(rèn)為覆巖離層注漿、矸石充填、條帶開采、原地重建抗變形房將是我國建筑物下采煤技術(shù)的發(fā)展方向。
