摘要
针对人工近距离接触测量获取岩体结构面信息工作效率低,劳动强度大等问题,开展了Sirovision岩体结构面三维不接触测量系统的研究。介绍了该系统的硬件组成及后处理软件的具体功能,提出了一套适用于该系统的岩体结构面信息采集方法与数据处理流程,并成功应用于铁蛋山铁矿的节理岩体调查与分析中。首先根据现场采集的调查区内原始格式二维图片,获得了真实坐标定位的巷道三维空间模型数据;然后进行了岩体结构面的数字化识别,并将得到的统计数据依据产状特征进行了分组,获得了不同节理组的空间方位统计信息;最后根据不同节理组间的相互位置关系,进行了基于后处理软件系统的楔形体结构分析,确定了危险块体的位置。上述研究成果可为矿山安全生产及工程参数优化提供参考。
Aiming at the low efficiency and labor-intensive of obtaining the information of rock mass structural surface byartificial close contact measurement,the Sirovision three-dimensional and non-contact measurement system of rock mass struc-tural surface is researched. The hardware composition and specific features of post-processing software of the system are intro-duced, the suitable method of obtaining rock mass structure surface information and the flow of data processing are proposedand applied to survey and analyze the jointed rock in Tiedanshan iron mine successfully. Firstly, according to the original for-mation of two-dimensional images obtained in the investigation area ,the three-dimensional roadway space model data with realcoordinates is got. Then, the rock mass structure surface is digitally identified, the obtained indentified data are grouped on thebasis of occurrence so as to obtain the spatial orientation of different joints group. Finally, according to the positional relation-ship among different joints group, the wedge of the structure is analyzed based on the post-processing software system to deter-mine the location of dang^lous structural body. The above research can provide some reference for the mine safety productionand optimization of engineering parameters.
