Measuring method of a coal mine roadway local slope measuring instrument

Abstract

The invention discloses a method for measuring a local slope measuring instrument of a coal mine roadway. The measurement and value of the relevant values ​​of the roadway slope; the control box mainly includes the control circuit board, touch screen, single-chip microcomputer and battery, and the control box is used for the calculation and display of the relevant values ​​​​of the roadway slope. The measurement steps are divided into two steps: 1. Before measuring the slope, place the measuring instrument on the horizontal plane for benchmark calibration; The slope value is read. The invention is a portable coal mine roadway local slope measuring instrument, which is not affected by the dim line of sight in the roadway. It mainly automatically measures the local slope of the coal mine roadway ground through a geometric algorithm. The calculation idea is simple, and the measurement and calculation of the slope can be quickly completed. High precision.

Description

technical field [0001] The invention relates to the field of coal mine detection, in particular to a measuring method for a local slope measuring instrument of a coal mine roadway. Background technique [0002] Mine roadway is a general term for various underground spaces excavated in different directions, at different inclination angles, according to different sections and lengths in different rocks, serving different ranges and used for different purposes. Mine roadways are named and classified according to their spatial size, inclination direction, location, service scope and purpose. Since the coal mine roadway needs to measure the slope of its bottom after it is built, it is used for acceptance, but most of the current slope measuring instruments are improved based on protractors, which mainly read the measured values ​​​​by human eyes, and the measurement error is relatively large. Moreover, the coal mine roadway is dim and fuzzy, and auxiliary equipment such as light...

Since the coal mine roadway needs to measure the slope of its bottom after it is built, it is used for acceptance, but most of the current slope measuring instruments are improved based on protractors, which mainly read the measured values ​​​​by human eyes, and the measurement error is relatively large. Moreover, the coal mine roadway is dim and fuzzy, and auxiliary equipment such as lights are needed to read the value, which is not only troublesome to carry, but also has low measurement efficiency.
