Abstract Aiming at subject of strata movement and control caused by the mining with filling under buildings，railways and water-bodies(three-underground)，achieving together action of backfilling，coal pillar and roof load-bearing rock stratum was emphasized，and the conception of coordination support systems is put forward. Rock mechanics，strata control principle and others correlation theory are applied to analyze the supporting mechanism of backfilling，the supporting conditions of coal pillar and the process of mechanics action and the stability condition of the coordination support systems. Research shows that the supporting mechanism of backfilling act as the horizontal reinforce action at coal pillar and the vertical supporting action at roof load-bearing rock stratum；the horizontal reinforce action should meet the controlled condition for the purpose of greater holding power which coal pillar effect on overburden；The mechanics action of the coordination support systems with backfilling，coal pillar and roof load-bearing rock stratum experience four main stages including the accelerated subside of overburden，uniform speed subside，decelerated subside and steady in proper order. Moreover，it is found that the degree of compaction(Dr) and the packing fraction(Ff) bigger，these have more advantageous to integrity and bearing strength environment of the coordination support systems，and strata movement and ground subsidence can control as much as possible. At last，the coordination support systems theory is applied in the three-underground mining with filling of Zhouyuanshan mine. In order to reduce ground subsidence as much as possible，analytic result indicated that the degree of compaction(Dr) of backfilling raise to above 0.8，and the packing fraction(Ff) control above 90%.

Key words： mining engineering mining with filling coal pillar strata control coordination support systems
