煤岩裂隙钻孔光学窥视测定是基于数字图像相关方法(Digital ImageCorrelation,DIC)光学测量手段,基于室内光学测试技术,改进煤岩损伤与裂隙现场声光电综合测试装置,以碱沟煤矿+564m水平B3+6。急倾斜煤层工作面为例,经过对超前预爆破顶煤裂隙特征测定,定量分析了顶煤裂隙的数量、大小和倾角,确定裂隙方位,为安全开采提供保障。
The coal petrography crack drilling Digital Image Correlation (DIC) , and existing optics measurement is optics measure method based on room optics testing technology. The testing equipment for coal defect and crack field sound-light-electric is improved. Taking + 564 B3+6steep coal working face in Jiangou colliery for example, by the pre-blasting top coal crack feature measurement. The number, size and dip angle of the crack is quantitatively analyzed to ensure safe mining.
