Abstract Based on the drilling holes layout of grouting into overburden-separation of #4 coal seam in Huafeng coal mine，theoretical analysis，regional dynamic planning and indoor simulation experiment are employed. By analyzing existing technical problems including the short face length，wrong judgement of coal pillar and rupture steps which can cause low efficiency of reducing subsidence，a new method is issued including arrangement of dip grouting drilling holes with technology of overburden-separation continuous integration grouting and arrangement of strike grouting drilling holes with method of regional dynamic planning. With the result of simulation experiment，it is shown that there are some improvements in aspects of inadequate overburden mining，goaf activation caused by pillar failure and difficult separation below the conglomerate and so on with using the continuous integration technology. Finally，the method of layout of continuous integration grouting drilling holes along the dip direction below greatly thick conglomerate and layout of six grouting holes along the strike direction outside the roadway 80 m of face is employed. And results show that the extent of mining is adequate beneath the separation zone，and the efficiency of reducing subsidence reaches to 44.6% with recycling more than 9.4×107 kg of coal resources，and quantity of drilling work reduces by 930 m along the dip direction.

Key words： mining engineering overburden separation grouting filling mining extent efficiency of reducing subsidence regional dynamic planning
