Based on Shanxi Gaoping Kexing Malong Coal Corporation 3305 working face geological survey, using theoretical analysis and in-situ test method, the optimization of large cross section open cut supporting parameters was made, and the site industrial test, the results showed that the roof subsidence, two nearer and floor heave amount decreased significantly, the supporting effect was remarkable.
JI Dun-yun. supporting parameters optimization starting cut section of full-mechanized caving mining face technology research and application[J]. CCI, 2013, 36(8): 56-58，62.
