Abstract
To tackle the challenge of strong mine pressure occurrence in the ZF2822 working face of the Xiagou Coal Mine,achieve controllable transformation and beneficial utilization of disaster energy,and develop dynamic disaster prediction and dynamic control methods,this study conducts basic mechanical parameter tests of the surrounding rock,completes the precise detection scheme layout of overburden structure and multi-source data monitoring inversion,and carries out full-cycle evaluation and support optimization research on the mechanism of strong mine pressure occurrence in gob-side roadways with a hard roof and extra-thick coal seam,as well as its precise and efficient control.Based on an analysis of the geological occurrence and mining environment characteristics of the Mine,the spatial fracture morphology of the hard and thick roof,overburden movement laws,and the spatiotemporal characteristics of hard roof fracturing are investigated.An integrated collaborative control technology of"pressure relief-modification-anchoring"for the surrounding rock of the mining roadway in the ZF2822 working face is developed.A new theory of extra-thick coal seam mining is established,achieving benign regulation by artificially inducing the transformation of stored energy in the hard and thick roof into kinetic energy for top coal fracturing.This research holds significant value for coal mine safety production.关键词
