中文摘要：
采用数字式全景钻孔摄像系统，宏观探测了顶板围岩诱导致裂失稳崩落的裂隙形态，从裂隙的三维图像与空间坐标关系，对裂隙的产状和隙宽等参数进行了定量的数字化探测、处理与还原。运用统计学原理，对裂隙宏观形态的参数进行了统计，综合评价了矿岩诱导致裂裂隙扩展的定量关系。分析结果表明，数字式全景钻孔摄像系统可以直观可视和定量精细描述裂隙的形态。诱导裂隙发育、扩展以及裂隙的演化规律表明，回采扰动和强制爆破诱导耦合技术有利于顶板围岩致裂失稳崩落，从而达到诱导崩落顶板处理采空区的目的。
英文摘要：
The crack forms have been studied for the caving of roof rock resulting from induced fracture by digital panoramic borehole camera system. The quantum digital detect, treatment and reduction have been done on the shape and wideness of cracks based on the relationship between three-dimensional image and coordinate space. With principle of statistics, the statistic was made on the parameters of Macro form of cracks. The analysis shows that digital panoramic borehole camera system is visible and can quantitatively describe the form of cracks. It is showed that the coupling technology induced by stopping and disturbance, forced explosion will be used to induce crack in the surrounding rock on the roof so as to result in the caving of roof in mined-out area.
