Adaptive Analysis on Shield Hydraulic Support for Shallow Buried Coal Seam in Cuncaota No.2 Coal Mine

Through the observation of strata behavior laws at 13107 working face of Cuncaota No.2 Coal Mine and the analysis of ZY7600-12/24 type two-column shield hydraulic support on face roof support and control effect, using fully mechanized coal face hydraulic support reasonable resistance determination method, key strata control theory, and fully mechanized coal face support strength regression formula calculation method, the reasonable support resistance parameters for 3-1 coal seam of Cuncaota No.2 Coal Mine are calculated and analyzed. The adaptability of shield hydraulic support for shallow buried coal seam is researched and studied comprehensively.
