Abstract

Disclosed are a ground surface simulating device and an experiment method thereof. A sample separation plate is arranged in an experimental box, probers are arranged at the bottom of the experimental box, a rack-gear transmission assembly is arranged on one external side of the experimental box and is connected with a motor, a three-dimensional scanner is arranged on the motor, vibrators are arranged at the lower end of the sample separation plate, and the vibrators, the motor and the three-dimensional scanner are controlled by a computer. Through modeling, probing, scanning and final data analyzing, ground surface settlement data and analyzer rules can be obtained, and scientific bases can be provided for prediction of geological disasters caused by ground surface settlement.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a surface simulation device and an experiment method thereof. Background technique [0002] In the process of coal mining, a large number of goafs inevitably appear, resulting in surface subsidence. The ground subsidence, subsidence, mountain cracking and other geological environmental damages caused by coal mining and the geological disasters induced by them have become a problem that affects the production and safety of coal mines, the change of land surface in mining areas and the ecological environment, and restricts the sustainable development of economy and society in coal mining areas. important factor. Accurate prediction of coal mining subsidence before mining is a prerequisite for restricting mining and controlling coal mining subsidence. How to timely and accurately monitor the subsidence of the surface and grasp the deformation law of the surface becomes particularl...
