Zusammenfassung:The invention discloses a diamond wire saw cutting blasting assembly well forming method which comprises the following steps: (1) designing a rectangular raise section according to ventilation requirements and geological conditions, and designing a plurality of guide holes vertically tunneled from top to bottom; setting one or two guide holes as drilling process inspection pretreatment holes, performing drilling process inspection pretreatment on the guide holes, detecting the reliability of the drilling process, and obtaining process parameters of each round of well completion cutting drilling; (2) accurately drilling the cross section of the raise; (3) sequentially cutting edge lines of the courtyard by adopting a diamond wire saw according to a mode of first transverse and then longitudinal to form a suspended rock block; and (4) carrying out segmented blasting ore breaking to form the courtyard. The method has the advantages that the safety is high, the well wall is smooth and regular, the labor intensity
