Forecasting and early warning system and method for mine pressure of underground working face of coal mine

Abstract

The invention relates to a forecasting and early warning system and method for mine pressure of an underground working face of a coal mine, and belongs to the field of coal mining. The forecasting andearly warning system mainly comprises a monitoring module and a forecasting and early warning module. The forecasting and early warning method comprises the steps that based on the calculating formula and the statistic law of the theory related to mine pressure, relevant information of the working face at different periods is collected and processed, the mine pressure strength of the working faceis prejudged, the position and the strength of each time of weighting are forecasted, before-mining pressure early warning before mining of the working face is achieved, and long-time early warning and real-time early warning in the mining process of the working face are achieved; and meanwhile, corresponding prevention and control measures of a high mine pressure disaster are given based on dataof large database in the background. According to the forecasting and early warning system for the mine pressure of the underground working face of the coal mine, all-time forecasting of the positionand the strength of weighting of the comprehensive mechanized working face and weighting dynamic early warning are achieved, guiding significance for support selection and prevention and control andtreatment of the high mine pressure disaster is provided, and safe and efficient exploiting of the working face is ensured.

Description

technical field [0001] The invention is a system and method for predicting and early warning of mine pressure in an underground working face of a coal mine, and is especially suitable for predicting and early warning of the initial pressure and periodic pressure and the pressure position of the comprehensive mechanized working face in the field of coal mining. technical background [0002] In the process of coal mine underground mining, the pressure on the working face is an important factor affecting the safe and efficient production of coal mines. Predicting the position and intensity of the pressure on the working face in advance has important guiding significance for safe and efficient production. Although the periodic pressure has a certain pressure step distance, affected by many factors, the pressure step distance fluctuates within a certain range, and the pressure intensity is also different. Modern coal mining technology widely uses more mechanized and intelligent w...

Problems solved by technology

Although the periodic pressure has a certain pressure step distance, affected by various factors, the pressure step distance fluctuates within a certain range, and the pressure intensity is also different.

Modern coal mining technology widely uses more mechanized and intelligent working face hydraulic support equipment, which has the functions of pressure monitoring, pressure early warning, and automatic height monitoring, but its pressure early warning is only given when the pressure of a single support exceeds the set value. It cannot reflect the pressure on the working face
