Relationship Between Natural Height Difference Δh and Slope Double Track Central Distance
With the study on the calculation process of the natural height difference in the double track slope of the mining engineering design manual,the calculation of Δh、ΔL、ω was found that the horizontal projection of the double track central distance was the basis of the calculation.The space relationship between the actual double track central distance,angle and route was not found.But the Δh was a very important middle parameter affected to the calculation of the max height difference ΔH in the high and low track roadway and the selection of the vertical curve radius.With establishment of the relationship between the Δh、ΔL、ω calculation and the actual double track central distance,the Δh could be correctly calculated.The design drawing obtained would be more accurate and could be better to guide the production.
