Description

Technical Field

[0001] The present invention relates to the technical field of mine transportation, and in particular to an integrated mine transportation system and a transportation method. Background Art

[0002] The mine's electric locomotive, monorail crane, rubber-tyred trackless vehicle and other transportation systems are the main arteries of the mine's auxiliary transportation system and are an important guarantee for the safe and efficient operation of the transportation system. At present, the auxiliary transportation systems of coal or non-coal mines in most areas adopt inclined shaft string lifting, gentle slope surrounding rubber-tyred trackless vehicles, conventional monorail crane transportation and other methods, all of which have certain risks and shortcomings and need to be solved urgently; The potential risk of broken ropes and runaway cars in the inclined shaft hoisting transportation method has always been its shortcoming, pain point and difficulty in safety management. With the continuous development and extension of mines, the hoisting distance is getting farther and farther, and the bottom drum of the tunnel is deformed, the transportation speed is reduced, the transportation capacity is insufficient, and the safety risk is also increased accordingly; the gentle slope surrounding trackless rubber-wheeled vehicle transportation has the characteristics of no reprinting, wide application range, fast transportation speed, strong transportation capacity, and low transportation cost. However, as the coal seam is buried deep and the mining depth of the mine is large, the auxiliary transportation method is too long, the safety factor is also increased accordingly, and the well construction period is too long and the investment is too large. Less; conventional monorail crane transportation has the characteristics of no reloading, wide application range, strong transportation capacity, small size, maneuverability, unlimited transportation distance, small tunnel section, small turning radius, and free operation on branch lines. However, due to the limitations of tunnel support strength and stability and tunnel roof conditions, the carrying capacity of monorail cranes cannot be too large, and the maximum operating speed is about 2m / s, which is slow. With the increase of mining depth, the transportation distance is longer, and more sets of diesel engine monorail cranes are required, which need to be replaced at the bottom of the well. There are many operating links and the operating efficiency is not high. In addition, if Figure 1 As shown in the figure, the inclined shaft train and the conventional monorail crane development tunnel can only run one train at a time, forming a straight-line mine tunnel, such as Figure 2 , 3 The gentle slope shown is surrounded by rubber-wheeled vehicles, which cannot be relocated and are long circular mine tunnels; In summary, with the continuous development and extension of mines, the lifting distance is getting farther and farther, and the deformation of the tunnel bottom drum makes the winch lifting have the problems of reduced transportation speed, insufficient transportation capacity, and increased safety risk; the monorail crane locomotive has the problem of long transportation distance, needing to be equipped with more monorail cranes, and needing to be replaced at the bottom of the well, with many operating links and low operating efficiency; the trackless rubber-wheel transportation has the problem of a wide vehicle body, a wide safety gap for the tunnel, and high requirements for the hardness and unevenness of the tunnel bottom plate, and high initial equipment and mine construction investment. Therefore, the present invention proposes a mine integrated transportation system and transportation method to solve the problems existing in the prior art. Summary of the invention
