摘 要:矿井工业场地留设保护煤柱,并保证煤柱的长期安全稳定是工业场地设施及建筑物在服务期间不受采动影响正常使用的基础。通过分析矿井工业场地受保护等级的规定,明晰了不同等级建筑物增加围护带宽度的数值,从而确定受保护工业场地面积;论述了垂直剖面法留设保护煤柱的原理,依据煤层的赋存条件,设计了张家庄煤矿风井工业场地保护煤柱。工程实践表明,应用垂直剖面法设计的保护煤柱安全可靠,保证了煤层开采后风井工业场地的安全使用。Protecting coal pillars and ensuring the long-term safety and stability of coal pillars are the basis for the normal use of industrial facilities and buildings during the service period. Through the analysis of the protection grade of the mine industrial site, the value of increasing the width of the enclosure belt for buildings of different grades is clarified, so as to determine the area of the protect? ed industrial site. This paper discusses the principle of coal pillar protection in vertical section method, and designs the coal pillar protection in wind shaft industrial site of Zhangjiazhuang coal mine according to the occurrence condition of coal seam. The engineering practice shows that the protection coal pillar designed by the vertical section method is safe and reliable, which ensures the safe use of the industrial site of the wind well after the mining of No.8 coal seam.
