The effect of overburden separation dynamic development under key stratum on grouting for bed separation space was analyzed , in order to deal with the problem that the current bed separation growing technology can not prevent the key stratum from breakage , put forward the isolated section - grouting technology for overburden bed separation space , integrated the virtue of growing for bed separation space and partial extraction , the bed separation grouting bodies , key stratum and isolated section pillars were made to constitute the load - carrying body all together , and to reach the purpose of reducing subsidence effectively , increase the coal seam extraction ratio , and accelerate the development of isolated section - growing technology for overburden bed separation space
摘要分析了關(guān)鍵層下離層動態(tài)發(fā)育對離層充填的影響，針對目前離層區(qū)充填工藝不能阻止覆巖關(guān)鍵層初次破斷的問題，提出了“覆巖離層分區(qū)隔離注漿充填”技術(shù)，它綜合離層充填與條帶開采技術(shù)的優(yōu)點，通過離層區(qū)充填置換或減小分區(qū)隔離煤柱寬度，使“離層區(qū)充填體關(guān)鍵層分區(qū)隔離煤柱”形成共同承載體，從而達到有效減緩地面沉降的目的，提高了煤層采出率，促進了覆巖離層充填減沉技術(shù)的發(fā)展。
