Method for loading explosive in fields in mixed manner on basis of underground explosive loading trucks

Abstract

The invention relates to the technical field of underground mine blasting explosive loading operation, and discloses a method for loading explosive in fields in a mixed manner on the basis of underground explosive loading trucks. The method includes steps of enabling lift arms to shift automatic tube conveying machines to places near blast holes under remote control; turning and shifting the automatic tube conveying machines to align the head ends of explosive loading tubes with the blast holes; starting the automatic tube conveying machines to automatically convey the explosive loading tubes into the blast holes; starting emulsion pumps and sensitizer pumps when the explosive loading tubes are conveyed to the bottoms of the blast holes, and respectively delivering emulsion substrates and sensitizers into the blast holes via the explosive loading tubes. The automatic tube conveying machines are arranged at the front ends of the lift arms. The method for loading the explosive in the fields in the mixed manner on the basis of the underground explosive loading trucks in an embodiment of the invention has the advantages that emulsion explosive mixed loading operation in the fields is automated, accordingly, the explosive loading efficiency can be improved, the labor intensity can be relieved, the safety of operators can be guaranteed, and blast effects further can be enhanced.

Description

technical field [0001] The invention relates to the technical field of explosive charging operations in underground mine blasting, in particular to an on-site explosive mixing method based on an underground explosive charging vehicle. Background technique [0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in air, water, earth and rock media or objects to achieve the intended purpose. In mining operations, blasting is an essential link. [0003] At present, in the process of charging and blasting in underground mines, the charging method is still mainly manual loading. Many people are required to participate in the loading of explosives, and a charging platform needs to be built near the blast hole. The operator works on the charging platform near the blast hole, which makes the charging process very dangerous. In addition, the charge tube used for loading explosives is sent into the blast hole by ...
