Ration determination method of mine hydrogeology inside and outside border hydraulic power nature artificial neural network (ANN) technology

Abstract

In the prior art, mine hydrogeology inside and outside border hydraulic power nature is determined according to single index qualitative analysis or even theoretical analysis. The invention discloses a ration determination method which utilizes multiple indexes, qualitatively analyzes and studies from multiple aspects to determine the mine hydrogeology inside and outside border hydraulic power nature, analyzes and studies various control factors of the mine hydrogeology inside and outside border hydraulic power nature, collects data, builds an ANN mathematical model, simulates, evaluates, predicts, and develops an information system. The ration determination method has the advantages of analyzing and studying various control factors of the mine hydrogeology inside and outside border hydraulic power nature, adopting the multiple indexes, analyzing and studying from multiple aspects to determine the mine hydrogeology inside and outside border hydraulic power nature, introducing the ANN technology into a determination method of the mine hydrogeology inside and outside border hydraulic power nature, and having enough precision.

Description

technical field [0001] The invention relates to a quantitative analysis method of coal mine hydrogeological conditions, in particular to a quantitative determination method of ANN technology for hydraulic properties of inner and outer boundaries of mine hydrogeology. Background technique [0002] The outer boundary of mine hydrogeology refers to the surrounding boundaries of various water-filled aquifers / groups in the mine field, mainly including fault boundaries, large-scale rock mass boundaries, outcrop boundaries, and surface water boundaries; The inner boundary of the well field with the hydraulic connection of the aquifer / group, including the inner boundary of the point-like karst collapse column type, the inner boundary of the linear fracture / zone or fold axis or fracture-intensive belt type, the inner boundary of the narrow-strip concealed outcrop type, and the planar inner boundary The inner boundary of the fracture-crack network type and the inner boundary of the th...

Problems solved by technology

[0004] However, the determination of the hydraulic properties of the inner and outer boundaries of mine hydrogeology in the prior art is to determine the hydraulic properties based on a single index qualitative analysis, or even theoretical analysis.

[0005] The hydraulic properties determined by the qualitative analysis or even theoretical analysis of the existing technology based on a single index are often completely different from the actual situation revealed by mine production, resulting in many problems, which are far from meeting the needs of coal industry production and safety
