[0002] Fissure peeping in top coal is a kind of technology that uses specially designed peeping instrument to observe and detect the fissure in coal roof or top coal. This technology drills the peeping instrument into the coal seam through borehole, and makes detailed observation and record of the fissure in coal seam, including the occurrence, development, size, shape and distribution of fissure.
