Group Of Ore Mining Aquifer Structure Variation Driven By Similar Material Simulation Studies

Demand of coal resources in recent years, guide the coal production increaseddramatically, due to the large number of mining, coal mining caused by fracture, overlyingstrata subsidence, the aquifer structure is destroyed, so the water in the aquifer changed thestorage condition, causes the regional groundwater resource redistribution, causing someWells springs dry, causing the destruction of the water conservancy facilities and the ruralpeople and draft difficulties. So the study of coal mining is of great significance to thedestruction of the aquifer.This topic through the study of the data collection of the study area, in understandinggeological condition, hydrogeological condition in the study area, on the basis of in-depthstudy of mining-induced fracture rules, similarity theory knowledge. Combined with thegeological conditions of mining area, rock mechanics parameters in coal core stratigraphiccolumn the graph is a prototype, based on the similarity principle, to generalizedhierarchical simulation area rock similar material simulation experiment scheme design, theguarantee model and the initial conditions and boundary conditions of similar cases,simulate single ore and the group of the coal bed mining experiment, to study the coal stratastructure deformation, damage and driven by the space-time distribution of mining-inducedfractures, through analysis of geophysical exploration and drilling data validation, it isconcluded that mining fissure development regularities and group of aquifer in the processof ore mining spatial structure change rule.
