摘要
根据保护煤柱的基本理论,结合其现有的计算方法,分析了当前垂线法保护煤柱设计方法的一些不足,建立了完整解析数学模型。通过分析研究,得出了保护煤柱的边界和相应压煤量的计算公式,并运用编程语言将垂线法确定保护煤柱进行了自动化实现。通过与传统方法的比较,在提高计算精度的同时,缩短了计算时间,提高了工作效率。
According to the basic theory of protective coal pillar,combined with the existing calculation methods,we analyzed some deficiencies in protective coal pillar design by vertical method,and established a complete analytical mathematical model. Through the analysis,we got a formula for calculating the protection coal pillar boundary and pressed coal quantity,and achieved automation by using programming language to determine the protective coal pillar with vertical method. By comparing with the accuracy of the traditional method,it shortens the computational time and improves work efficiency.
