“ Three soft” coal seam hosting was unstable, a large of coal resources was lost in goaf of western Henan Province. Based on this situation, combined suspension support with whole roof beam combined with shearer and blasting mining in local area was adopted, from the management and technology angle, many measures were taken to control coal quality of repeated mining, gas disaster and goaf water disaster prevention were strengthened to ensure mining safety, which provided reference for repeated mining technology of similar mine.
