煤矿井下地质编录是煤矿的一项基础性技术工作,而影像地质编录技术是一项实用的新技术。按照现有影像地质编录方法需要在拍摄部位布设足够数量的控制点,但掘进工作面附近环境复杂难以布设控制点,为了能够在掘进工作面使用摄影测量手段顺利地进行影像地质编录工作,提出了一种新的近景摄影测量控制方法,利用巷道指向激光与铅垂线进行掘进工作面影像的绝对定向。模拟试验和现场试验表明,该方法是一种适合煤矿巷道掘进工作面影像地质编录的绝对定向方法,点位精度可控制在1 cm以内。

An underground mine geological compilation was basic technological work of the coal mine and the video geological compilation technology was a new p ractical technology. According to the available video geological compilation method, there would be sufficient number control points required for the layout of the camer a locations, but the complicated environment near the heading face was hard to set up the control points. In order to successully conduct the video geological compilati on work with the photographic survey means in the heading face, a new close-range photographic survey control method was provided. The guidance laser and the plu mb line in the gateway were applied to the absolute orientation of the driving face projection. The simulation experiment and the site experiment showed that the metho d was the absolute orientation method suitable for the video geological compilation of the mine gateway driving and the location accuracy could be controlled within 1 cm
