Abstract:
Based on the project conditions of super-large inclined angle, many turnings and long haulage distance of track inclined drift at island longwall working face in the Tenth shaft of Pingdingshan Tian'an Coal Mining Company Limited No.3 Coal Mine, we use endless rope towing vehicle continuous transportation system and loop wire rope shuttle car to pull auxiliary transport equipment and instead of multiple scheduling winches and achieve auxiliary transport with long haulage distance, uphill and downhill and many turnings. After selection calculation, continuous transport system of endless rope towing vehicle with series SQ-120/132P was used. The quality of track was requested, at the same time, we established a force analysis theoretical model on shuttle train during it turning, introduced the relationship between theoretical running speed and the quality of shuttle train. With the increasing of shuttle train quality, its normal running speed will decrease. Through field industrial test, the reasonable ranging of running speed for shuttle train under different towing conditions was obtained. Conclusions of the study could avoid overturned and off track accidents of shuttle train, which improves the safety performance and application range of continuous transportation system with endless rope towing vehicle.
