specific Embodiment approach

[0163] In this way, by analyzing the position of the coal mining machine and the change characteristics of mine pressure, collecting effective data, and establishing a data analysis model, the pressure step distance of the fully mechanized mining face can be automatically calculated. The specific implementation is as follows:

[0164] For data collection and centralized storage, 1#, 4#, 7#, ... 133#, 136#, ..., (3*N-2) support right pressure and shearer position are selected as the research objects in the working face. Collect data every 30s, using SQL Server database as the main storage platform for system management and real-time data; image 3 As shown, if the pressure is lower than 250bar, it is considered that the safe mine pressure is divided into one category, and each increase of 50bar is a category and a color is assigned. The darker the color, the greater the pressure on the roof, which is conducive to visual display. 350bar is used as the pressure threshold, and if...

Abstract

The invention discloses a method and electronic equipment for automatically measuring the pressure step distance of fully-mechanized mining faces. The effective continuous increasing sequence and the continuous decreasing sequence are used as the coal cutting cycle sequence; in each coal cutting cycle sequence, the maximum working resistance of the shearer when passing the hydraulic support is calculated to form the whole working The pressure matrix of the surface, the pressure matrix includes the maximum working resistance of each hydraulic support in each coal cutting cycle sequence; the pressure step distance of the entire working face is calculated according to the pressure matrix. The invention does not require manual participation, and through automatic data collection and automatic calculation of programs, it can realize the automatic calculation of the pressing step distance by the computer, the mine pressure data analysis efficiency and accuracy are higher, and the production cost of coal mine enterprises is greatly reduced.

Description

technical field [0001] The invention relates to the technical field related to coal mines, in particular to an automatic measurement method and electronic equipment for the pressure step distance of a fully mechanized mining face. Background technique [0002] Roof disaster, as one of the five major disasters in coal mines, has always been at the forefront of various coal mine accidents due to its characteristics of multiple points and wide areas and difficult control. Strengthening mine pressure monitoring and early warning is an effective means to prevent roof disasters. Fully mechanized mining face Calculation of pressure steps is an essential link in roof management. The existing calculations of pressure steps are all through manual observation and recording, and regular statistical analysis. However, this method is time-consuming and laborious, and has poor timeliness, and accuracy cannot be guaranteed . [0003] In recent years, due to the rapid development of sensors...
