The invention discloses a bedding area hydrofracturing method by utilizing control of interception. The bedding area hydrofracturing method mainly aims at coal beds which are low in hardness, high ingas content and low in gas permeability. Firstly a conventional method is adopted to conduct test on coal bed crustal stress, geological information and a fracture development situation, a fracturingarea is divided into four parts according to the test result and being centered on a fracturing hole, and the fracture development direction is monitored by utilizing inspection holes and a microearthquake technology. When fracturing fluid or a signal monitored by microearthquake happens on one inspection hole in the fracturing direction, fracturing operation is temporarily stopped, an interception hole is constructed and blockage is conducted at the position 30 cm away from the fracturing hole in the fracturing direction, after the interception hole is solidified, fracturing operation is continued, till the four parts are completely fractured. The bedding area hydrofracturing method solves the problem that the extension direction of the fracture in the hydrofracturing process cannot be clearly detected, the result is reliable, and the targets of fracturing and permeability improvement of a coal bed area can be achieved.
