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
摘要分析了关键层下离层动态发育对离层充填的影响，针对目前离层区充填工艺不能阻止覆岩关键层初次破断的问题，提出了“覆岩离层分区隔离注浆充填”技术，它综合离层充填与条带开采技术的优点，通过离层区充填置换或减小分区隔离煤柱宽度，使“离层区充填体关键层分区隔离煤柱”形成共同承载体，从而达到有效减缓地面沉降的目的，提高了煤层采出率，促进了覆岩离层充填减沉技术的发展。
