矿山开采沉陷教学中关于地表移动观测站设计的两点探讨

为了保证地表移动观测站设计的可靠性,本文提出采用边界角及其修正量替代移动角和修正量进行观测线长度设计,可作为传统观测站长度设计的有效检核条件;利用沉陷预计方法确定沉陷盆地主断面来设计观测线位置,可有效检核基于传统角量参数设计观测线位置的可靠性。最后将本文提出的观测站设计可靠性检核条件用于某矿工程实践,有效的确保了地表移动观测的可靠性,取得了良好的工程应用效果。

Discussion about the Design of Surface Movement Observation in the Mining Subsidence Teaching

In order to guarantee the reliability oi＇ surface movement observation station design, the viewpoint is put forward which is take the boundary angle and its correction instead ot in movement angle for observation line length design, that can be used as an dfective check condition oi＇ traditional observatory length design; Prediction method is used to determine the subsidence basin main section to design the position of observation line, which can effectively check the reliability of the observation line position based on traditional angular parameter design. Finally put the observation station design relia bility check conditions used in the mine engineering practice, which effectively ensure tbe reliability of surface movement observation and has obtained the good effect of engineering application.
