摘要
在综合分析大量文献的基础上,简要总结了保护煤柱留设方法(垂直断面法、垂线法、数字标高投影法、变形预计法等)的特点及应用现状,并对目前保护煤柱留设方法存在的问题及发展趋势作了简单阐述,对矿区地表建(构)筑物保护煤柱设计的生产实践具有指导意义。
Referring to the analysis of references , This paper summarizes the characteristics and actuality of application for the methods in setting protective coal pillars （Vertical section method, Weeping line method, Digital elevation projection, Deformation- estimating method, etc） , and described briefly the research problems and the tendency in setting protective coal pillars, which has great guiding significance to design the protection pillars for the surface building.
