Large-diameter blasthole blasting in mines is generally loaded with on-site mixed explosives trucks. For example, the BCLH-15 on-site mixed ammonium oil explosive truck is used. The manufacturer is Huaihai Industrial Group Shanxi Huifeng Special Automobile Co., Ltd. After the mixed explosive truck is loaded with explosive raw materials, it drives into the blasting operation site. After the explosive raw materials are prepared into explosives through the on-board system, the explosives enter the large-diameter blasthole through the screw pump outlet to complete the blasthole filling. However, due to the small aperture of small-diameter blastholes, it is impossible to directly use on-site mixed explosives trucks for loading, and the blasthole filling can only be completed by manual loading. The specific process is: after receiving the finished rolled or bagged explosives from the explosives warehouse, it is transported to the blasting operation surface, and the explosives are manually loaded into the blasthole.
