摘　　要：文中统计分析了11座特高压线塔所处位置煤层的埋深、松散层厚度等地质采矿条件;结合《规范》经验值、两个工作面的地表移动变形实测值,并综合考虑山体采动滑移附加影响,分析得到了地表移动角值参数;采用垂线法,理论计算了保护煤柱尺寸,并通过地质块段法对煤柱压煤量进行了估算。In this paper,the geological and mining conditions such as the coal seam buried depth and the loose layer thickness of 11 ultra high voltage(UHV)line towers were analyzed statistically,combining with the empirical value of"Specification",the measured surface movement deformation value of two working faces,and considering comprehensively the additional influence of the mountain mining sliding,the surface movement angle value parameter was analyzed and obtained,and the protective coal pillar size was calculated theoretically by using the vertical line method,and the pressed coal quantity of the coal pillar was estimated by using the geological block section method.
