Mining Drill Bits

The production system of Mining Industry is a complex system composed of many links.

In blast hole drill bits and coal mining drill bits   , complicated geological and hydrologic conditions, thick alluvium of topsoil, many quicksand layers, large water inflow, large well diameter, deep wellbore, and often concentrated operation scale, as well as high temperature, high pressure and high formation stress in the deep well, will greatly aggravate the severity of underground complexity and the difficulty of treatment.

Some problems should be solved according to the characteristics of coal mine drilling:

The problem of increasing drilling speed

Prevention and treatment of well collapse, diameter reduction, drilling drop and other accidents.

Anti-deviation technology.

High temperature resistance。

Problems of cutting tools in deep well construction.

Therefore, it is necessary to perfect the structure of the large-diameter bit.With the increase of drilling fluid density and well depth, the fluid column pressure exerts a pressure holding effect on the broken cuttings at the bottom of the well, and the broken cuttings from the cone bit are not easy to leave the bottom of the well under the action of differential pressure, resulting in the formation of a cushion at the bottom of the well, reducing the crushing efficiency, etc. Reasonable bit structure will speed up the flow of cuttings in the bottom hole, improve the crushing efficiency, accelerate the drilling speed and shorten the drilling cycle.

As well as improving the life of the roller bit, the service life of the roller has a great impact on the construction cost of drilling well. The life of the roller bit mainly depends on the life of seal, bearing and parent.

GREAT Mining tricone bit is utilized for blasting hole open pit mining. Depending on the different formations of customers, mining drill bit manufacturers can offer different product and types of drill bits used in mining,the sizes ranged from 6 3/4" to 16".

Mining tricone bit, we recommend 532、632、642、722 etc.

The fishing tool is the most widely used tool for overhauling oil and water wells. There are many types of fishing tools in drilling. According to the types of falling objects in the well, they can be divided into five categories: spear tools, overshot tools, junk basket, hook fishing tools, and cutter tools.

Balancing valve types

1. Static Balance Valve: It is also called Balance Valve, Manual Balance Valve, Digital Lock Balance Valve, Double Position Regulating Valve, etc. It changes the flow resistance through the valve by changing the clearance (opening) between the spool and the seat to achieve the purpose of regulating the flow rate. Its object of action is the resistance of the system, which can distribute the new water in proportion to the design calculation. Each branch increases or decreases in proportion at the same time, and still meets the flow demand of part of the current load.

2. Dynamic flow balance valve: It is also called self-operated flow control valve, self-operated balance valve, constant flow valve, automatic balance valve, etc. It automatically changes resistance coefficient according to the change of system working condition (pressure difference). In a certain range of pressure difference, the flow through can be effectively controlled to maintain a constant value, that is, when the pressure difference before and after the valve increases, the flow through the valve can be maintained by the action of automatic closing small. On the contrary, when the pressure difference decreases, the valve opens automatically and the flow rate remains constant.

3. Self-operated differential pressure control valve: it is also known as dynamic differential pressure balance valve, differential pressure controller, stabilized variable synchronizer, differential pressure balance valve, etc. It uses differential pressure to adjust the opening of the valve, and uses the change of pressure drop of the valve core to compensate for the change of pipeline resistance, so as to keep the differential pressure basically unchanged when the working condition changes. Its principle is that it can effectively control the constant pressure difference of the controlled system within a certain flow range. That is to say, when the pressure difference of the system increases, it can ensure that the pressure difference of the controlled system increases through the automatic closing of the valve. On the contrary, when the pressure difference decreases, the valve opens automatically and the pressure difference remains constant.
