ZDY6500L crawler type mechanical cavitation drill for coal mine
Save worry and effort, enjoy low price!!
YK drill company has recently developed and produced mechanical hole expansion and caving equipment for coal mines in view of the actual situation of difficult pressure relief management and low gas drainage management efficiency in tunnel pressure relief control, gas drainage control and other engineering projects. This equipment adopts hydraulic mechanical jacking. The rod type control principle is mainly used for rock formation expansion and cave creation. It can be used for hole expansion support of soft rock in coal mines, impact rock pressure control, roof cutting and pressure relief, as well as gas prevention and hole bottom caving in coal seams of various hardnesses.
This equipment adopts the principle of hydraulic mechanical control outside the hole, so that the all-round hydraulic crawler drilling rig can provide hydraulic ejector driving function, and arrange the corresponding control valve group, and use the control valve group to control the hydraulic oil circuit, cooling water, and wind. According to different The construction requires a mechanical core-rod driven drill rod for thrust-driven long-distance output. The front end of the mechanical core-rod driven drill rod is equipped with a mechanical ejector reamer and a drill bit used with the reamer.
Hydraulic propulsion mechanical caving fully hydraulic crawler drilling rig products are mainly used in the field of mining engineering. The main technical indicator is hydraulic mechanical caving at the bottom of the hole. The quality level is in the leading position in the country. During the R&D and production process, YK Drill Company actively pays attention to intellectual property rights. Protection work, patent application based on innovation points for patent protection, involving patent application
A mechanical floating wing slag-discharging hole expansion and cavitation technology (Patent No.: ZL202010701768.7),A push rod jacking type hole expander (Patent No.: ZL202010922779.8),A hydraulic propeller (patent number: ZL202010890623.6),A mechanical ejector drill pipe (Patent No.: ZL202021510251.1),And apply for the mining safety marking certificate issued by the National Mining Safety Marking Center (certificate number: MED200476).
This product integrates the design of drilling rigs and drilling tools. During the testing process in major mining areas, its extraction concentration increased by 4.5% compared with carbon dioxide fracturing technology. Compared with high-pressure hydraulic punching and caving technology, high-pressure hydraulic punching and caving technology The current market price of the complete set of technical equipment is about 1.5-2 million yuan. The mud pump occupies a huge cost space. The hydraulic propulsion mechanical caving and fully hydraulic crawler drill does not need to purchase a mud pump to provide power. This alone can save costs. It is around 30%, so the hydraulic propulsion mechanical caving fully hydraulic crawler drilling rig produced by our company has irreplaceable competitive advantages in terms of market application prospects and customer acceptance.
Through the analysis of the technical data obtained from the test, the soft coal seam hydraulic mandrel gas permeability mechanical caving equipment can not only meet the requirements of caving construction, but also use low-pressure water or pressure air to discharge slag in the hole to prevent high-pressure water from causing irregularities in the hole wall. Destroy, reduce the phenomenon of gas injection holes, and reduce the free activity of gas. In terms of economic value, the hydraulic mandrel gas anti-reflection mechanical cavitation equipment developed does not require an additional high-pressure pump station, which can save part of the construction cost. The single-hole hole forming efficiency is high; the low-pressure slag discharge in the hole has the functions of hole protection and collapse prevention. The advantage of the hole is that the drilling is well-organized, thereby maintaining long-term effective gas drainage and indirectly improving the gas drainage efficiency.
