| description | The invention discloses a construction method, particularly discloses a construction method for hanging top blasting treatment of an underground mine, and belongs to the technical field of mining production processes. According to the construction method for hanging top blasting treatment of the underground mine, the treatment effect is good, the hanging top treatment time can be greatly shortened, and the treatment cost can be greatly reduced. The construction method comprises the following steps that firstly, on the basis of an existing blast hole in the hanging top, an explosive pot and a treatment blast hole are obtained through at least one time of reaming blasting, then quantitative explosives are loaded into the explosive pot through the treatment blast hole, and finally the blasting treatment work of the underground mine hanging top is completed through the blasting of the quantitative explosives.
