Blasting method for shallow-buried goaf of strip mine

The invention provides a blasting method for a shallow-buried goaf of a strip mine and belongs to the technical field of engineering blasting. The blasting method comprises the following steps that step1, properties, occurrence conditions and geometric spatial characteristics of ores around the goaf are confirmed; step2, the safety thickness of a top plate above the goaf is confirmed, perforating equipment is selected, and a perforating scheme is designed; step3, hole net parameters of goaf top plate loose blasting and lateral throwing blasting are confirmed, and a charging structure and a detonating network are designed; step4, the muck pile size is estimated; step5, goaf volume balance calculation is performed, and the blasting collapse volume is confirmed; step6, blast hole arranging, charging and filling are performed; and step7, the detonating network is connected, detonating is performed, and the caving filling effect is observed and recorded. According to the blasting method for the shallow-buried goaf
