Sandstone rock strip mine blasting method

The invention discloses a sandstone rock strip mine blasting method which comprises the following steps: drilling a plurality of blast holes in a working surface according to blasting design requirements; blasting explosives are loaded into all the blast holes; a first primer detonator and a second primer detonator are arranged in each blast hole, the first primer detonator is made to be close to the top of the blasting explosive, and the second primer detonator is made to be close to the bottom of the blasting explosive; plugging the orifice of each blast hole by using a plugging object; and the first primer detonator and the second primer detonator are detonated, and explosion of the blasting explosives in all the blast holes is achieved. The sandstone rock strip mine blasting method has the advantages of being high in sandstone blasting quality, low in blasting cost and high in mining and loading operation safety. 本发明公开一种砂岩岩石露天矿爆破方法，砂岩岩石露天矿爆破方法包括以下步骤：根据爆破设计要求，在工作面上钻设多个炮孔；向每个炮孔内装入爆破炸药；向每个炮孔内装入第一起爆雷管和第二起爆雷管，
