| 摘 要： | 针对目前传统留设保护煤柱的方法存在的问题进行了分析,基于保护地面一点的原理,得出了保护地面一点的公式,进而提出了似椭圆法留设保护煤柱的原理,给出了留设保护煤柱的方法与步骤.实例分析表明,与传统垂直断面法相比,似椭圆法留设保护煤柱可以大大解放“三下”呆滞煤量.依据保护煤柱围护带留设的目的,通过对似椭圆法留设保护煤柱的精度进行分析,确定了似椭圆法留设保护煤柱围护带的宽度,并对其围护带宽度的合理性与适用性进行了探讨.

| Abstract: | Some problems with traditional design protective coal pillar method are analyzed.Based on the principle of protection a point on the ground,the formula of protection a point on the ground is obtained.The paper puts forward the principle of similar ellipse method to design coal pillar for protection of buildings,and the method and steps are proposed.In the light of practice instance and compared with traditional vertical section method,similar ellipse method to design protective coal pillar can liberate "three underground" stagnant coal greatly.Besides,according to designing additional band of protective coal pillar,the precision of method of similar ellipse method is analyzed,and additional band size of protective coal pillar is determined.Its reasonability and applicability are probed. |
