Deep Shaft Connecting Chambers Dynamic Response Model Experiment Research

During the recent years, in order to settle the problem of energy's scarcity, a wave of new mines'constructing has been starting in the north and the middle part of Anhui Province. Because the coal buried deep ,the ground pressure is high and the geological condition is complex, accidents often happen and bring us not only economic losses but also casualties. For security reasons, it's not allowed to delay the study about chambers system in deep well.The joint between coal mine well and tunnel (horsehead) loaded in deep well's key position. Its cross-section is higher and wider than general tunnel's, so while excavating, the country rock is disturbed again and again. In the meantime, country rock's stress, broken area and displacement are influenced. More dangerous, the well shaft and chamber system's stability can't be ensured. This paper designs different dynamic process to study the structural stress law of chambers system which located at the bottom of deep well. In addition, similar simulating experiment reflects the phenomenon of chambers system's disturbing. More over, according to second well of actual measurement data of Zhuji coal mine in Huainan, disclosure horsehead's dynamic deformation damage law from different kind factor effect the country rock and get the construction program in favor of country rock's stabilization. The study has high reference value to guide the future designation and construction of deep shaft chamber system.
