A method for intelligent rock strata control in fully mechanized mining face

Abstract

The invention discloses an intelligent rock strata control method for a fully mechanized mining face, comprising the following steps: S1, establishing a coal wall stability discrimination system; S2, collecting a support operation flow system library, a fully mechanized mining face working resistance database, and a fully mechanized mining face Support posture model library; S3, collect real-time three-dimensional dynamic images of the roof and coal wall of the fully mechanized mining face; S4, obtain the pressure parameters of the collected working face and the state parameters of the coal wall by analyzing the collected data of steps S2 and S3; S5, input the data obtained in step S4 into the coal wall stability discrimination system, and the coal wall stability discrimination system outputs the judgment result; when the judgment result is that the coal wall is stable, then this data is saved in the database as a case, When the coal wall is unstable, the judgment result is fed back to the electro-hydraulic control system, and the electro-hydraulic control system implements protective measures on the coal wall until the coal wall is stable, and saves the data as a case in the database.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to an intelligent rock formation control method for a fully mechanized mining face. Background technique [0002] At present, coal mines are at a critical point of change. Under the premise of highly developed and integrated coal mining automation and informatization, the requirements for intelligent coal mining have become very urgent. One of the key contents in intelligent coal mining is intelligent strata control. Since the object of coal mining is a complex geological body, the coal mining process is not only affected by the structure, structure, bedding, etc. of the geological body itself, but also by the mining The secondary stress brought about by this will greatly affect the stability of the surrounding rock of the working face. The traditional control of the surrounding rock of the working face mainly relies on manual identification and judgment, and the hydraulic support is con...

AI Technical Summary

Problems solved by technology

Due to the subjective influence of human identification and obvious aftereffects, the control of the rock strata in the working face often fails to achieve timely and accurate control, which affects the mining progress and production efficiency of the working face. At the same time, with the vigorous advancement of intelligent mining, In order to realize the goal of less people and unmanned work at an early date
