根据我国采矿突水和试验观测资料,论证破坏采场顶底板隔水岩层至某一深度,造成间接顶底岩溶含水层之水突入或滞后突入矿井的力源是矿山压力、水压力和地应力。用“超静定梁”的理论描述采场直接隔水顶底板内矿山压力分布特征,并考虑了矿(岩)层倾角、顶底板移近值、顶板冒落岩块充填采空区等因素,论述 According to the data of mining water inrush and experiment in our country, it is demonstrated that the source of water which intrudes or lags behind the water in the indirect top-bottom karst aquifer into the mine by destroying the top and bottom aqueduct strata in the stope to a certain depth is the pressure of mine, water pressure and in-situ stress . The “statically indeterminate beam” theory is used to describe the characteristics of mine pressure distribution in the directly grounded roof and floor, taking into account the factors such as the dip angle of mine and rock floor, the approach value of roof and floor, and the gob of roof caving block , Discussion
