Problems solved by technology

[0003] When the dust removal equipment of some existing drilling rigs is used for drilling dust removal, negative pressure suction is usually used to suck all the dust and large-sized gravel out of the drilling, which will easily cause the failure of the dust removal equipment and consume a lot of energy. Electric energy increases the cost, affects normal use, and cannot remove dust when drilling continues

Embodiment Construction

[0026] use Figure 1 to Figure 5 An exploratory hole drilling method of the present invention is described as follows.

[0027] like Figure 1 to Figure 5 Shown, a kind of exploratory hole drilling method described in the present invention, this method comprises the steps:

[0028] S1: Set multiple sets of limit columns on the inner side of the annular water tank in the drilling rig for exploration engineering, and set two spherical arc plates on the limit columns, and the lower spherical arc plate is fixedly connected with the limit columns. The impact of the circular arc plate expands the spraying area of ​​clean water for dust removal; by setting two spherical arc plates on the limit column, and the spherical arc plate below is fixedly connected with the limit column, when the annular water tank follows the knife When the plate vibrates up and down, the clear water on the upper spherical arc plate and the inner side of the annular water tank will move up a certain distanc...

Abstract

The invention belongs to the technical field of drilling and particularly relates to a prospecting borehole drilling method, comprising the steps of setting multiple groups of limiting posts in a circular water trough in a prospecting engineering drill rig, and sleeving each limiting post with two spherical arc plates, with the lower spherical arc plate fixedly connected to the limiting post and the two spherical arc plates impacting to enlarge water spraying area for dust removal; setting acceleration springs between the top ends of the limiting posts in the circular water trough of the prospecting engineering drill rig and the spherical arc plates above so that the acceleration springs help enlarge impact force between the spherical arc plates; setting an arc balloon between a wavy plateof the prospecting engineering drill rig and a cutterhead, arranging an exhaust hole in the outer side of the arc balloon, and spraying compressed air from the exhaust hole to blow off sprinkled clear water; starting an electric push bar and a first motor in the prospecting engineering drill rig to perform drilling. The method herein has the advantages that water spraying area is enlarged, dust removal efficiency is effectively improved, and physical health of workers is protected.

Description

technical field [0001] The invention belongs to the technical field of drilling, in particular to a method for drilling an exploratory hole. Background technique [0002] A drilling rig is a complex set of machines, which consists of machines, units and mechanisms. A drilling rig is a mechanical device that drives a drilling tool to drill underground to obtain physical geological data during exploration or mineral resource development (including solid ore, liquid ore, gas ore, etc.). Also known as drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or lift the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to ascertain the conditions of underground geology and mineral resources. Drilling rigs produce a lot of dust during use, which endangers the health of workers. [0003] When the dust removal equipment of some existing drilling ...
