Mining hydraulic power operation machine

Abstract

A mining hydraulic power operation machine comprises a host machine, an execution table, a clean water pump station, a hydraulic pump station and a switch cabinet, wherein a flexible steel pipe control instrument and a high pressure water control instrument are mounted in the execution table; the host machine is connected with the flexible steel pipe control instrument through an oil pipe and the high pressure water control instrument through a water pipe; the flexible steel pipe control instrument is connected with the hydraulic pump station through an oil pipe; the high pressure water control instrument is connected with the clean water pump station through a water pipe; and the execution table, the clean water pump station and the hydraulic pump station are electrically connected with the switch cabinet through power cables respectively. The mining hydraulic power operation machine has the advantages that the structure is compact, and is greatly simplified; underground pore-forming positions and directions in a coal mine can be adjusted; requirements for pore-forming, pore-dredging, broaching, slotting, fracturing and other omnidirectional underground operation in a mine can be met; the work is stable, safe and reliable; the occupied space is smaller; and the mining hydraulic power operation machine is very suitable for underground coal mines and other circumstances with narrow spaces.

Description

technical field [0001] The invention belongs to the technical field of coalbed methane mining equipment, and in particular relates to a mining hydraulic operating machine used for hydraulic hole forming, hole dredging, hole reaming, slotting and fracturing of gas drainage holes in coal mines and on the ground. Background technique [0002] There are many high-gas mines in my country, and they have the characteristics of high coal seam gas content, high pressure, poor air permeability and difficult drainage. At present, the average mining depth of key state-owned coal mines in my country is about 420 meters. With the further increase of mining depth, the ground stress and gas pressure also increase, and the difficulty of gas drainage also increases. Through years of experimental research, my country has gradually formed a set of underground gas drilling methods and techniques suitable for the characteristics of coal mines in my country. The gas drainage effect of undergroun...

AI Technical Summary

Problems solved by technology

However, due to the following characteristics, it cannot be used in underground coal mines: (1) The direction is not adjustable, and it is all downward, which cannot meet the needs of multi-directional drilling in underground mines; (2) The distribution of equipment is scattered, and the base, roller, The injection heads are scattered and occupy a large area, which is difficult to adapt to the use of small underground spaces
