Embodiment Construction

[0056] The technical solutions of the present invention will be further described in detail through specific embodiments below in conjunction with the accompanying drawings. In the present invention, two embodiments are mainly used as examples. The first one takes the prediction of roadway mine pressure appearance characteristics during the influence stage of 110102 transportation and tunneling in Shanxi Shouyang Ji'anda Mine as an example; the second one takes Shanxi Duanwang Group as an example. Take the prediction of roadway mine pressure appearance characteristics in the influence stage of 30102 transportation and mining in Youzhong Mine as an example.

[0057] First example:

[0058] 1) Layout of the station

[0059] In this embodiment, the whole process of mine pressure manifestation at the two sides of the roadway is predicted by collecting the displacement data of the two sides of the roadway. The measuring instruments used may be distance measuring instruments such a...

Abstract

The invention discloses a method for predicting mining roadway mine pressure appearance data, and belongs to the technical field of mine roadway surrounding rock control. Using the prediction variation model of mine pressure manifestation data to perform nonlinear regression on the actual difference of a series of mine pressure manifestation data, that is to obtain the definite function expression of the change speed and cumulative change of mining roadway mine pressure manifestation data, and then The mine pressure appearance characteristics of the mining roadway are obtained. The method for predicting the mine pressure appearance data of the mining roadway of the present invention can quickly and efficiently predict the mine pressure appearance characteristics of the mining roadway, and has a wide application range.

Description

technical field [0001] The invention relates to a method for predicting mining roadway mine pressure appearance data, and belongs to the technical field of mine roadway surrounding rock control. Background technique [0002] Among the three types of roadways in coal mines, the development roadway, the preparation roadway and the mining roadway, the mining roadway has a short service life, so its support design can only meet the normal use during the mining period. Compared with the other two types of roadways, mine pressure is stronger. Measuring the surface deformation convergence of the mining roadway is one of the must-measure items during the excavation and mining of the mining roadway. The basic method is: immediately after the coal and rock mass is excavated, some anchor points are buried on the two sides and the roof of the roadway as the measurement base point , use the monitoring instrument to measure the slight change in the distance between any base points within...
