Mining lot exploiting and monitoring method based on interferometric synthetic aperature radar (InSAR) technology

Abstract

The invention provides a mining lot exploiting and monitoring method based on interferometric synthetic aperature radar (InSAR) technology. The method includes the steps of obtaining a probability integral method model coefficient of a mining area adjacent to a mining area to be detected, using a radar sight line directional deformation field, obtained through the InSAR technology, of a mining lot to be detected, using the length, the width, the thickness, an exploiting depth, a trend azimuthal angle and a central point coordinate of a working face of the mining area to be detected as unknown numbers, and enabling the unknown numbers and a probability integral method model coefficient of the mining area adjacent to the mining area to be detected to be brought in the probability integral method model, then using a genetic algorithm to search and obtain a parameter value of the working face of the mining area to be detected, finally, using the working face parameter value obtained through the genetic algorithm as an initial value of a mode searching method, and obtaining the accurate working face parameter value of the mining area to be detected through iterative search. The mining lot exploiting and monitoring method overcomes the defects in the prior art that only an approximate exploiting location can be obtained in the process of exploiting monitoring to the mining area, and underground goaf detailed parameter information can not be obtained accurately, greatly expands the application space of the InSAR technology in the mining area, and provides a mining area exploiting fine monitoring method which is low in cost and large-scale.

Description

technical field [0001] The invention relates to a mining mining monitoring method based on InSAR technology. Background technique [0002] With the increasing demand for coal resources and the contradiction between the dwindling resources is becoming more and more prominent, driven by the interests, there have been unapproved and unplanned mining in many areas. This kind of mining will not only lead to the destruction and waste of resources, hinder the country's orderly management of resources, but also produce many unidentified gobs, which are prone to water inrush accidents, thus threatening the life and property safety of mines and staff. In addition, underground mining will lead to subsidence and deformation of the surface, causing deformation and damage to buildings and structures above the goaf. Therefore how to accurately obtain the depth H of the underground mined-out area, the center point coordinates (X c ,Y c ), goaf direction length D 3 , tend to be long D 1...
