Abstract

The embodiment of the invention discloses an automatic positioning device for rock roadway blasting holes, and belongs to the field of coal mine rock roadway blasting. The automatic positioning devicecomprises a controller, a shell, a laser positioning component, and a controller, wherein a control chip and a first Bluetooth transmission chip connected with the control chip are arranged in the shell; the laser positioning component comprises a laser ranging assembly and a second Bluetooth transmission chip in cooperative communication with the first Bluetooth transmission chip; and the controller is mounted on a drilling heading machine, the laser positioning component is hung on a roadway roof and can move in the roadway heading direction, and the controller is used for receiving the distance between the laser positioning component and a roadway head-on, sent by the laser positioning component, and calculating and determining-be-tunneled blast holes and the laser positioning component and a horizontal axis according to the distance, and then sending control signals to control the laser positioning component to emit laser to the roadway head-on according to the included angle so as to realize positioning of the to-be-tunneled blast holes. The difficult problem of inaccurate positioning of the blasting blast holes in actual construction can be solved, so that the construction quality of the blasting blast holes is improved.

Description

technical field [0001] The invention belongs to the field of coal mine rock roadway blasting, in particular to an automatic positioning device for blasting holes in rock roadway blasting. Background technique [0002] In order to improve the excavation level of coal mine rock roadway, medium and deep hole blasting excavation technology has been more and more applied in coal mine rock roadway excavation. The spacing and row spacing of the blasting holes have a significant impact on the blasting effect. In the actual blasting construction, there are often situations where the blasthole drilling does not match the actual blasting design, resulting in problems such as low efficiency of rock roadway blasting, poor roadway forming quality, and large damage to surrounding rock. [0003] Tracing it to its root cause is that positioning inaccurately causes during blasthole drilling. Contents of the invention [0004] In view of this, the present invention aims to provide an autom...
