Problems solved by technology

[0004] The purpose of the present invention is to provide a quick test method for underground geomechanical parameters of coal mines and a deep hole peeping instrument to solve the existing problems of low work efficiency, complicated test work, and a large amount of manpower, material resources and time; it is difficult to make a reasonable design. ; The test of several parameters cannot be carried out in the same rock drilling, which is not an explosion-proof problem

Embodiment Construction

[0018] see Figure 1 to Figure 5 , the steps of the testing method of the present invention during implementation are as follows:

[0019] A. At first set up a vertical test hole 2 of 20-30m in the coal mine underground roadway 1, and send the electronic viewing mirror 5 of the peeping instrument 4 into the test hole 2 with the delivery rod 3 .

[0020] B. Observe and record the surrounding rock structure of the entire test hole 2 to determine the size, orientation, and distribution of structural surfaces such as bedding, joints, and cracks in the surrounding rock structure, and find out several complete sections. The specific steps Including using the peeping instrument 4 and the electronic speculum 5 to test the image and zoom in, direction positioning, camera and information storage; through the test hole 2 to observe the development of structural surfaces such as roadway surrounding rock bedding, joints and cracks, Recording and analysis can determine the size, orientatio...

Abstract

A geology mechanics parameter speedy test method and the equipment of underground colliery: drill test hole at operating face; measure the design value of the surrounding rock by sight scope which has lateral direction device deep-lying sightglass; speedy measure the stress state of the rock by using the method of hydraulic pressure leading split; then put the sightglass into the test hole, measure the split curve and direction by using the directional device on it; measure the intensity of resistant to compression and modulus of elasticity in the test hole. The invention offers a new method and the sight scope has double functions which are screen and save the images of front and side drilling-hole.

Description

technical field [0001] The invention relates to a method for rapidly measuring geomechanical parameters in coal mines and a deep hole peeping instrument used for implementing the method. The method and equipment can also be applied to underground rocks in other mining, construction, electric power, water conservancy, military and other departments Geomechanical testing of soil engineering sites. Background technique [0002] The surrounding rock of the roadway is an extremely complex geological body, and all work related to the surrounding rock is inseparable from the full understanding of the geomechanical parameters of the surrounding rock. Geomechanical parameters include surrounding rock structure, surrounding rock strength, and in-situ stress. Before the coal mine roadway layout, roadway and chamber support design, the geomechanical parameters must be tested to ensure the rationality of the roadway layout and support design and the safety of the roadway. [0003] Due ...
