关于回采矿房给定测量方向、形成房间矿柱和测量其形状等方面的工作,在科学技术文献和技术标准文件中论述得并不充分,而且实际使用的测量方法不能保证达到很高的测量质量。矿山测量方法主要决定于回采空间的高度和设计的房间矿柱的形状。当矿房高度不大(3～4米)时,测点固定在顶板上,并用普通的铅垂线法给定测量方向。当回采矿房的高度大于4～5米时,难以在顶板上固定测点,所以,采用交会法或者划线标明矿柱位置。
The work on the given measurement direction of the mining house, the formation of the pillars of the room and the measurement of its shape are not adequately addressed in the scientific and technical literature and technical standard documents and the actually used measurement method can not guarantee a high measurement quality. The method of mine measurement mainly depends on the height of the recovery space and the shape of the pillars in the room designed. When the mine is not high (3 to 4 meters), the measuring point is fixed on the roof, and the normal plumb line method is used to determine the measuring direction. When the height of the mining house is more than 4 to 5 meters, it is difficult to fix the measuring point on the roof plate. Therefore, the pillars position shall be indicated by intersection method or underline.
