The invention relates to a coal mine hard roof pressure relief method, in particular to a coal mine hard roof directional fracturing control method. The coal mine hard roof directional fracturing control method solves the problem that an existing coal mine hard roof fracturing control method cannot achieve accuracy and high efficiency. The coal mine hard roof directional fracturing control methodcomprises the following steps that a, a lateral suspension top not-caved roof of a roadway is selected as a directional fracturing control area, a drilling machine is adopted to drill holes at the interval of L, the drilled holes are linearly arranged in the length direction of the roadway, each drilled hole is located in the vertical plane in the length direction of the roadway roof and forms anangle theta with the roadway roof, wherein L is 1-3 m, and the angle theta is 60-80 degrees; b, complex perforators are assembled; c, each drilled hole is internally provided with one complex perforator, all the drilled holes are sealed, leads of the complex perforators in all the drilled holes penetrate through the hole seal to be led out of the drilled holes, the leads are connected with detonators at the outlets of the drilled holes, and all the detonators are connected with an detonation instrument; d, the detonation instrument is ignited, and operation is completed. The coal mine hard roof directional fracturing control method achieves accurate fracture generation of the coal mine hard roof.
