Mechanical coal seam hole making pressure relief device
In order to make ZDY series drilling rigs and CMS series drilling rigs have mechanical reaming function, our company has designed a more convenient mobile hole-making hydraulic device, which includes mechanical coal seam hole-making pressure relief device and supporting core rod jacking mechanical reamer, core rod jacking hole-making drill rod and hydraulic thruster, realizing rapid replacement in roadway and enabling ordinary drilling rigs to have mechanical reaming operation function.
Product advantages
● Easy to install-can be quickly adapted to various types of drilling rigs, without the need for drilling rigs to upgrade the well.
● Convenient transportation-the existing guide rails in the roadway can be used to quickly pull to the working face where the drilling rig is located.
● Independent control-with independent power and control system, does not affect the original performance of the rig.
The newly developed mechanical coal seam hole-making and pressure relief device and full hydraulic crawler mechanical hole-making equipment (patent number: ZL 202010922779.8, patent number: ZL 202010890623.6,) are widely used in the hole-making and hole-making construction of this coal seam and through-layer drilling in high-gas coal mines, and the hole-making construction of rock burst control, especially in the field of hole-making at the bottom of gas prevention and control holes in high-gas soft coal seams.
Mechanical hole reaming series products
This product adopts hydraulic mechanical control, no high-pressure pumping station, high hole rate, can effectively reduce the hidden dangers of mine disasters, can adapt to complex geological conditions, reduce equipment investment, improve construction efficiency. It has the characteristics of simple use, convenient operation, safety and reliability, which can better guarantee the safety and stability of coal mine production. It has become the preferred product for coal mine gas extraction, hole reaming and hole making and increasing permeability.
Working principle
Mechanical hole-making reaming series products provide axial thrust with hydraulic thrusters, realize long-distance high thrust output through mutual pushing of core rods of hole-making drill pipes, actively open the blade wing at the target position of hole-making, and automatically close the blade wing after hole-making. The core rod jacking type mechanical reamer adopts high-strength radial cutting blade height to adapt to the hole-making construction of complex geological conditions, and the operation process is controlled by the machine outside the hole, with high reliability.
After a large number of engineering construction verification, in the soft coal seam cavity construction, through low-pressure water or pressure air for hole slag discharge, to avoid the high-pressure water on the hole wall caused by irregular damage, with the advantages of hole protection, hole collapse prevention, drilling formation regularity is good, so as to maintain the long-term effective gas extraction, improve the gas extraction efficiency, shorten the gas extraction period. Compared with the carbon dioxide cracking technology, the extraction concentration of the product in the test process of major mining areas is increased by 4.5, compared with the high-pressure hydraulic punching hole-making technology, the water consumption is less, the disturbance to the stability of the coal seam is low, and the failure of drilling tools caused by hole collapse and drilling is greatly reduced. Our company's latest research and development of mechanical hole-making series of equipment and the market circulation of traditional hole-making equipment technology has irreplaceable performance advantages.
Main features of series products
1, the use of hydraulic mechanical control, without high-pressure pumping station, greatly reducing equipment investment and high-pressure safety risks;
2. Mechanical control outside the hole-making hole and visual active control of blade wing opening and closing greatly reduce the risk of tool damage in coal and rock alternating structure;
3, the use of a wide range, can meet the upward dip hole, horizontal hole, -15 degrees down dip hole, F4 within the medium hard and soft coal seam large diameter hole, and F8 within the small diameter soft rock hole construction;
4, mechanical hole-making process, less water consumption, low disturbance to the stability of coal seam, significantly improve the hole-making hole rate, the efficiency is more than 2 times of high-pressure hydraulic hole-making.
