摘要
根据生产剥采比不大于经济合理剥采比的原则,确定了留沟深度判定准则及直角留沟缓帮转向的特点,建立了以缓帮留沟高度为基本变量的最佳经济效益模型,得出了留沟总效益是关于留沟深度的三次函数,推导出了最佳留沟深度计算公式。并通过对我国黑岱沟露天煤矿实例的分析,论证了该模型的实用性。
According to the principle of the production stripping rate not higher than the economic rational stripping rate, thejudging criterion of the box retained depth and the features of the right angled box gently inclined slope turning were appliedto establish a optimized economic benefit model with the gent slope box retained height as a basis variation. The total benefitsof the box retained would be a cubic function of the box retained depth. A calculation formula of the optimized box retaineddepth was derived. The case analysis of Heidaigou Surface Mine in China proofed the practices of the model.
