Partially recyclable blast hole measuring and plugging device and application method thereof

Abstract

The invention provides a partially recyclable blast hole measuring and plugging device and an application method thereof. The device comprises a flexible scale rule, a material tank connected with theflexible scale rule and filled with plugging materials, a baffle plate provided with a trigger, a connecting sleeve used for connecting the material tank with the baffle plate, and a gravity hangingblock connected with the material tank, wherein the connecting sleeve comprises an upper sleeve, a lower sleeve and a spring buckle used for detachably connecting the upper sleeve and the lower sleeve; the trigger is used for controlling connection and disconnection of a circuit in the baffle plate; and a magnetic induction coil connected with the circuit is arranged on the upper surface of the baffle plate. By means of the mode, the gravity hanging block adsorbed to the bottom of the baffle plate can fall down after reaching the bottom of a hole through the trigger, the depth of the blast hole is accurately measured by sensing the tension change in the falling process of the gravity hanging block, and the plugging materials are driven to be sprayed out in the falling process of the gravity hanging block, so simultaneous measurement and plugging of the blast hole are achieved. In addition, the upper sleeve and the lower sleeve can be separated under the action of tension, so that partial recovery of the device is achieved.

Description

technical field [0001] The invention relates to the technical field of mining blasting, in particular to a partially recoverable blasthole measuring and sealing device and an application method thereof. Background technique [0002] Before blasting the mine stope, hole measurement and plugging are two procedures that must be implemented. In the process of hole measurement and plugging, the corresponding devices used are closely related to the accuracy of the measurement results and the plugging effect. Therefore, it is of great significance to design a suitable blasthole measurement and plugging device to improve blasting efficiency. [0003] At present, the hole measurement and hole plugging of mines are usually two separate work steps. Generally, the hole is measured first, and then the hole is plugged. Among them, the hole measuring process mostly adopts a simple hole measuring device composed of a water bottle or a wooden stick suspended by a wire rope, and the positio...

Problems solved by technology

However, since this method uses the limit barrel itself to block the blast hole, the entire device cannot be recovered after the measurement and plugging are completed, and each device can only be used once, which consumes a lot of equipment and costs relatively high
