摘要
Abstract
In view of the initial mining mine pressure law of the 1310 island working face in Xiaoyun Coal Mine,on-site monitoring is conducted from the initial support force of the hydraulic support,the end of cycle resistance,and the working resistance of the support.The research shows that the average initial support force of the support is 20.97 MPa,the step distance of periodic weighting is 13 m,and the dynamic load coefficient during the roof pressing period is 1.4-1.9;the end of cycle resistance of each measuring station's support is 23.04-36.96 MPa,accounting for 78.12%of the rated working resistance of the support.The existing support models meet production requirements.The research results provide a reference basis for roof management and surrounding rock stability control in the subsequent production of the working face.关键词
