Overlying strata hydraulics and rock mechanics monitoring method and system

Abstract

The invention provides an overlying strata hydraulics and rock mechanics monitoring method and system. The method comprises the following steps: water level data and air pressure data are detected through an automatic water level gauge and an air pressure gauge arranged in a hydrological monitoring hole in a mining area range; according to the solid tide effect and the air pressure effect of the well water level, corresponding inversion calculation models are selected under different conditions, and hydrogeological parameters of different coal seam overlying aquifers are calculated; distribution characteristics of three zones (a bending zone, a fault zone and a caving zone) can be visually and comprehensively known by obtaining hydrogeological parameters of coal seam overlying aquifers at different positions, and a new basis is provided for division of the three zones; and by acquiring space and time change characteristics of the hydrogeological parameters, time and space change rules of the hydrogeological parameters of the coal seam overlying aquifers in the coal mining process are monitored. According to the overlying strata hydraulics and rock mechanics monitoring method and system, the real-time influence of the mining process on the overlying strata can be identified.

Description

technical field [0001] The invention relates to the technical field of hydrogeological exploration, in particular to a method and system for monitoring the hydraulic and rock mechanics of overlying rocks. Background technique [0002] With the development of the economy and society, the continuous growth of the population and the accelerated pace of urban industrialization, the human demand for energy has also increased exponentially, so coal will continue to be developed and utilized as a traditional energy source. However, the goaf caused by coal seam mining will cause the overlying strata to rupture, which will inevitably affect the structure and properties of the overlying aquifer, causing a series of ecological and environmental problems such as groundwater leakage, water quality deterioration, ground subsidence, and ground fissures. Therefore, it is of great significance to understand the dynamic changes of the mechanical damage caused to the overlying strata during th...

Problems solved by technology

On the other hand, conventional hydrogeological tests and rock mechanics tests are often expensive, and continuous monitoring is almost impossible, which also makes real-time monitoring of overburden dynamics caused by mining impossible
