The Optimum Design Of The High Water Filling Along The Air Retaining Roadway

The cloud driving ridge mine 12305 face transport drift as the background, the use of numerical simulation and engineering monitoring method to study the high water alley next to the filling of gob roadway technology application. In this thesis, based on theoretical analysis, numerical simulation and engineering test, comparison and analysis of different along the roadway surrounding rock and backfill should strain development law, along goaf left lane and roadside backfill in the analysis of stress and deformation characteristics of the different mining stages that gob High Roadway side packing body position is more reasonable and the filling body force characteristics of regular understanding.The characteristics of initial setting time and strength of high water material with the water cement ratio 1.8, and the characteristics of damage characteristics and damage characteristics were studied. Finally through field measurement, on the high water alley beside filling body in the working face during mining stress are measured and analyzed to verify the size parameters of filling body, roadside backfill material ratio selection of rationality, the conclusion section work face mining, roadway and gob provide theoretical basis.This paper shows that the impact of the roadway can be divided into: first mining area(60 m from the working surface of the working surface 10 m ~ m), a mining dynamic impact area(measuring station 10 m ~-10 m), a mining area(measured at the working surface of-55 m ~-10 M), leaving the lane area(greater than-55 m).
