The autonomous positioning of tunneling equipment is the key to intellectualization and robotization a face. In this paper, method based on simultaneous localization mapping (SLAM) estimate body pose roadheader build navigation map roadway presented. terms estimation, an RGB-D camera used collect images, calculation model established random sample consensus (RANSAC) iterative closest point (ICP...

Visualization of objects using computer programs can greatly facilitate the external presentation projects coal industry enterprises. Modern graphics make it possible to embody very realistic models, and since creation 3D takes less time than their implementation. technologies allow you present model from all angles eliminate shortcomings identified in process its creation. Successfully impleme...

Abstract In order to improve the cutting efficiency of roadheader and address challenge monitoring load head pick, a simulation method was proposed using ABAQUS finite element software simulate at different depths under various conditions. According coal test, model developed Drucker-Prager as constitutive conical pick coal. The results analysis were compared with test results, reliability form...
