1. Main Purpose and Scope of Application

Crawler type full hydraulic directional drilling rig for coal mine is mainly used for the construction of various engineering directional drilling, such as underground gas drainage (drainage), purple injection for fire prevention, coal seam water injection, coal seam thickness, outburst prevention and pressure relief, water disaster control, geological exploration, etc. It is applicable to various coal seams and rock formations with rock firmness coefficient f ≤ 10.

The drilling rig can walk independently and turn in place. The roadway or drilling field is required to be more than 3m high, more than 4.5m wide, and more than 12m in section. It is also used for small-diameter diamond drilling for exploration of metal and non-metallic solid deposits, as well as engineering geological survey of civil buildings, highways, railways, bridges, dams, national defense construction, and engineering drilling for exploration of hydrological oil and gas fields, and grouting for lifting dams. The main supporting products of the drilling rig include hole bottom motor, mine measuring device while drilling, directional drill pipe, etc.

 2. Performance Parameters

ZYL crawler-type full-hydraulic directional drilling rig for coal mines (hereinafter referred to as drilling rig) is a full-hydraulic drive crawler-type directional drilling rig with the following characteristics:

The drilling rig has a high torque and a reasonable speed range, suitable for small-diameter diamond core drilling, and can also meet the requirements of large-diameter cemented carbide core drilling and various engineering drilling.

Large drilling feed and pulling capacity, easy to deal with special conditions in the hole. The drilling rig is simple in structure, reasonable in layout, small in size and high in transmission efficiency.

Centralized drilling rig operation, simple and convenient, flexible and reliable operation, large.

The whole drilling rig can be moved by itself, which is convenient and quick to install, and the preparation time is short. Large torque drilling rig, the maximum reaming diameter can reach 153mm, and the gas drainage efficiency is greatly improved.
