Discussion on the determination method of marginal grade of open-pit mining deposits
This article studies the methods for determining the marginal grade of open-pit mining deposits.Through literature review and data collection,the article summarizes the commonly used methods for determining the marginal grade of mineral deposits,including statistical methods,economic methods,engineering methods,etc.Then,based on the actual situation and demand,a method for determining the marginal grade of mineral deposits that comprehensively considers multiple factors is proposed.This method combines statistical methods,economic methods,and engineering methods to determine the marginal grade of open-pit mining deposits by considering multiple factors such as ore grade,mining costs,market demand,and environmental factors.The effectiveness of this method has been verified through practical case analysis.The research results indicate that this method can accurately determine the marginal grade of open-pit mining deposits and provide scientific basis for production decisions of mining enterprises.
