Abstract

In order to prevent surface movement and release “three under” coal, the new fly-ash cementing materials were utilized to take industrial test in Taoshan mine NO.3 colliery 95# coal-seam gob. The filling slurrys were transported into the filling bags in gob along the pipeline, taking away the pillar and template when filling materials were hard enough to support the roof, a great deal of filling bags formed filling strip, which replaced the protective pillar. The test results show that the compressive resistance of filling materials will reach 0.87MPa, 2.36MPa,3.38MPa and 6.38MPa when 8hours,1day,3days and 28days,and the initial setting time is 94minutes.Since the method is utilized in filling mining of Taoshan mine,the recovery ratio of coal raises effectively, the roof have no breakdown, the surface have little subsidence.
