摘要
结合相关资料,科学地分析了综合保护煤柱的留设方法和压煤资源开采的经济价值,讨论了垂直断面法、垂线法、数字标高投影法和变形预计法的相关内容,同时,还阐述了留设方法的特点及其应用状态。简要探讨了保护煤柱的留设方法的优缺点,以期为煤矿未来的发展提供一定的参考。
Referring to the analysis of references, this paper summarizes the characteristics and actuality of application or the methods in setting protective coal pillars, discusses 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.
