Mining medium-length hole arrangement pay-off instrument

Abstract

The invention relates to a mining medium-length hole arrangement pay-off instrument, and belongs to the technical field of arrangement pay-off devices. The mining medium-length hole arrangement paying-off instrument comprises a shell, a direct laser lamp and an annular laser lamp band are arranged in the shell, laser emitted by the direct laser lamp is perpendicular to annular laser emitted by the annular laser lamp band, and the shell is connected with a battery installation cylinder used for installing a battery. A rear cover is installed at the end, away from the shell, of the battery installation cylinder, a calibration piece used for guaranteeing that the annular laser is consistent with the arrangement face is arranged on the rear cover, an electric control switch is arranged on the shell, and the electric control switch is electrically connected with the direct laser lamp, the annular laser lamp band and the battery. The device has the beneficial effects that the construction efficiency and precision guarantee of medium-length hole paying-off can be effectively improved, the construction operation intensity of technicians is effectively reduced, and the device can be suitable for medium-length hole arrangement paying-off in various roadway environments of underground mines.

Description

technical field [0001] The invention belongs to the technical field of a rowing and unwinding device, and in particular relates to a rowing and paying off device for medium and deep holes used in mines. Background technique [0002] At present, underground mines mostly use the mining method of medium and deep holes segmented empty space and then filling. One of the construction steps of this method is that technicians carry out on-site measurement and setting out according to the arrangement design of medium and deep holes. The traditional way of setting out is tape measure and range finder. Combining, or using professional measuring instruments such as theodolite or level to set off the line, the former has problems such as insufficient accuracy and low efficiency, while the latter has problems such as cumbersome transfer stations, low efficiency, and heavy operations, and due to the irregular cross-section of the roadway on site, the passage The more difficult it is to ada...

[0002] At present, underground mines mostly use the mining method of medium and deep holes segmented empty space and then filling. One of the construction steps of this method is that technicians carry out on-site measurement and setting out according to the arrangement design of medium and deep holes. The traditional way of setting out is tape measure and range finder. Combining, or using professional measuring instruments such as theodolite or level to set off the line, the former has problems such as insufficient accuracy and low efficiency, while the latter has problems such as cumbersome transfer stations, low efficiency, and heavy operations, and due to the irregular cross-section of the roadway on site, the passage The more difficult it is to adapt to the traditional method, therefore, there is an urgent need for a mine-used medium-deep hole arrangement convenient setting-out instrument to effectively solve the current mismatch between the accuracy of the medium-deep hole arrangement and the demand, Low efficiency and high intensity technical problems
