REENGINEERING OF ALGORITHM FOR MINING PLOUGH PARAMETERS TO IMPROVE ITS MANEUVERABILITY IN THE PLANE OF A SEAM



The issues of design of mining plough F-1 ensuring continuous multi-point attack extraction of coal are discussed. The key parameter of the mining plough is its capacity conditioned by ground conditions, machine design and operating regime. The theoretical, technical and operation aspects are considered. Of particular interest is design of the advance system of the mining plough to the face with the sustained straight forward motion of the ploughing tool in the plane of a seam. The plough mobility system consists of three subsystems and interacts with the ambient medium via the ploughing tool, base frame and support mechanisms. The possible schemes of the ploughing tool advance to the face are described. The schemes include three processes of the plough advance in the seam: with respect to the seam plane, hypsometry and thickness. The analysis of the actual procedure to calculate design parameters and motion control mechanisms of the plough in the seam plane shows that the calculation of the plough capacity disregards the ploughing tool advance parameters with respect to the hypsometry and thickness of the seam. In connection with this, the article suggests reengineering of the algorithm to calculate characteristics of the plough advance control system with a view to taking into account the ploughing tool motion, which will refine the machine design parameters. The case studies of improvement in the fully mechanized longwall technologies of underground coal mining are presented.
