Research on intelligent and precision mining technology based on transparent geological big data

Transparent working face is currently an important research direction of intelligent mining and an important way to realize unmanned mining. Aiming at problems such as poor application effect of memory cutting, low sensor accuracy, low application rate of big data fusion, and it is unable to make independent perception, decision-making and adjustment according to the changesin the geological conditions of working face. Therefore, on the basis of the continuous progress of coal mine geological exploration means and exploration accuracy and the continuous progress of coal science and technology equipment level, the application of " intelligent and accurate mining based on transparent geological big data" technology has been explored to further improve the company' s intelligent mining technology level.Through geopfrysical exploration methods such asdrilling, roadway surveying and groove wave exploration and other geopfrysical means to build a more accurate three-dimensional model of the transparent working face, plan the cutting template in advance, and then jointly apply the inertial navigation technology, radar positioning technology and big data analysis and decision-making technology to continuously correct the cutting template, and finally complete the precise control of the shearer and frydraulic support through the underground precision control center. This technology upgrades the current "intelligent mining 1.0" stage based on memory cutting to "intelligent mining 3.0" stage based on transparent geological planning cutting, realizing the technological leap from traditional memory cutting to three-dimensional spatial perception and automatic cutting, which has strong adaptability and practicability. © 2021 The authors.
