Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] It should be noted in advance that, in order not to feel redundant, the following will describe the experimental method embodiment of the present invention in detail in combination with the principle, structure and application of the experimental device embodiment of the present invention.

[0029] A test box is prepared, which includes a cuboid box body 1 and an upper cover 11 covering the box body 1. A through hole is provided in the center area of ​​the upper cover 11 to facilitate the exposure of the shaft to the outside.

[0030] According to the principle of equal structural rigidity between the prototype and the model, the well shaft and Matoumen model 2 were made of tinplate to simulate the shotcrete structure there. Such as figure 1 , the shaft and horse head door model 2 includes a shaft 21, a roadway 23 and a horse ...

Abstract

The invention provides a deep-vertical-well ingate three-dimensional physical model experiment apparatus and a method. The apparatus comprises an experiment box used to place a shaft, an ingate model and filling surrounding-rock similar material, an optical-fiber measure system which comprises multiple optical fiber arranged in the experiment box and an optical-fiber data reading module connected with the multiple optical fiber, an electrical-method measure system which comprises multiple electrical-method measuring lines and a measuring-line data reading module connected with the multiple electrical-method measuring lines, a resistor-type strain sensor measure system which comprises multiple resistor-type strain sensors and a resistor data reading module connected with the multiple resistor type strain sensors, and a loading system which comprises a hydraulic cylinder, a reaction frame and a hydraulic control module; and the hydraulic cylinder is connected with the hydraulic control module, and the hydraulic cylinder is arranged between an upper cover of the experiment box and the reaction frame. The apparatus and the method are capable of comprehensively analyzing the dynamic response problem of ingate surrounding rock, and realizing dynamic mechanical response analysis on surrounding rock under different excavation conditions.

Description

technical field [0001] The invention relates to the field of mine construction engineering, in particular to a three-dimensional physical model experiment device and method for a horse head gate of a deep shaft. Background technique [0002] Matoumen refers to the part where the shaft of the coal mine shaft is connected with the roadway at the bottom of the mine. As a key part of the mine, it is the transfer point for equipment, materials and personnel. The main features of the horse head gate are special location, large design section and long service life. [0003] As new mines get deeper and deeper, the dynamic mechanical response of Matoumen surrounding rock and lining during construction is an important issue that affects the safety of support. During the construction of the Matoumen of the deep shaft, the stress and deformation characteristics of the Matoumen lining structure and surrounding rock are relatively complex, and the physical model experiment is an importan...
