Abstract

The invention provides a multivariable-based Taiji group limestone aquifer water inrush risk classification and discrimination method. The multivariable-based Taiji group limestone aquifer water inrush risk classification and discrimination method comprises the steps of S1, screening Taiji group limestone water inrush risk classification and discrimination variables; S2, performing Taiji group limestone water inrush risk classification according to variables according to variables, and the Taiji group limestone water inrush risk classification includes S21, safety types including the top platesafety type and the bottom plate safety type; S22, roof Taiji group limestone aquifer water inrush dangerous types including the roof water inrush dangerous type-no supply type and the roof water inrush dangerous type-supply type; S23, bottom plate Taiji group limestone aquifer water inrush danger types including a bottom plate too-grey single water inrush danger type-no supply and a bottom platetoo-grey single water inrush danger type-supply; S24, the bottom plate Taiji group and the Ordovician limestone aquifer associated with a water inrush dangerous type; and S25, collapse column and fault through water inrush danger type.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a method for classifying and judging water inrush risks of limestone aquifers of the Taiyuan Formation based on multivariables. Background technique [0002] At present, the North China-type mining areas that mainly produce coal in northern China, from Xuzhou, Zibo, Feicheng, and Yanzhou in the east, to Weibei, Shaanxi in the west, from southern Liaoning in the north, to Huainan and Pingdingshan in the south, are almost all affected by the bottom of the Carboniferous Permian coal measures. The influence of Taiyuan Formation limestone aquifer and Ordovician limestone strong aquifer. The limestone aquifer of Taiyuan Formation is directly water-filled aquifer in the lower group of coal mining in North China type coalfield. When the lower group of coal seam is mined, water inrush accidents in the Taiyuan Formation aquifer on the roof and floor frequently occur. Judging from the d...
