The law of energy dissipation in rocks and the dynamic fracture criterion clearly state: "When the loading energy is less than a certain threshold value, the loading energy does not participate in crack propagation at all, and all is useless dissipation energy; when the loading energy reaches the dynamic fracture criterion, the rock is dynamically destroyed, and the reactive energy dissipation energy is about 15%." Taking this theory as a starting point, the rock rotary drilling rig must have a large pressure capacity and large power head power (large torque and high speed). First of all, under the action of high pressure, the rock can realize the penetration of rock joints and the formation of cracks, and the cohesion disappears, so that it can be separated from the rock mass only by overcoming the friction force.

Holding roses, making wishes, eating cakes, and singing happily! Work hard and hope for a more brilliant career! In the journey of life, I spent thirty years in a hurry. Busy life already did not remember his birthday. However, the company for our birthday party forever fixed in my mind, became my heart forever moved! Flowers, exquisite cakes, let us feel the warmth of home; the gentle smiling faces of leaders and colleagues, and sincere blessings made us suddenly filled with warm happiness. filled with sweet, moving taste. When the candles are lit, the budding lotus blossoms

Do you know the matters needing attention of rotary digging machine drill pipe
Rotary drilling machine drill pipe is widely used in construction, especially in the selection of drill pipe, according to the geological choice, can choose the appropriate rotary drilling machine drill pipe. Drill pipes and bits can only be used for the drilling of pile holes, and are not allowed to be used for soil transfer, handling or leveling of the construction site. Never immerse the drill in liquid concrete. The drilling operation can only be started when the drill bit touches the bottom of the hole. When drilling into the sand layer or pebble layer, the machine should pay special attention to it. When drilling, the footage should not be too deep at one time, otherwise it will cause the hole wall to shrink and make the drill barrel wall and

Rig operation: operation skill mainly lies in pressurization
From the outside, the rotary drilling rig gives the feeling of being very tall, and it feels like the handle after entering the cab. There are many buttons, which generally gives people a complicated feeling. However, the fact is also true. From the positioning of the machine to the auxiliary working condition, and then to the drilling under the main working condition, there are indeed many actions required. However, in order to open the rotary drilling rig well, pressure is the most important among the many operating actions! The pressurization we mentioned here is not blindly downward pressurization through the handle, but to control the pressurization intensity and pressurization time for different rock and soil bottom layers. The routine is as follows: lifting suspension point floating long floating point pressurization short stroke pressurization long stroke

Basic concepts about geology and geological exploration
Geological exploration is already the most effective means to understand the geophysical properties. As a geologist, understanding the basic concepts of geology is the basis for entering this industry. The earth is composed of three layers: the crust, the mantle and the core. The crust is formed by the accumulation of various rock layers, and its depth is about 30 kilometers. The geological exploration we often say is carried out in this area, and the general drilling depth is not More than 1 kilometer. Geological exploration is the use of drilling equipment on the surface of the earth's crust for a certain depth of geological drilling, through the analysis of drilling core samples to analyze the ground below the rock or water layer of the basic situation. To understand the geological situation, we must first understand

Production Advantages and Application Scope of Friction Welding Grooving Drill Pipe
The combination of grooving drill pipes requires welding and various welding methods. Among them, friction welding grooving drill pipes are very popular with customers in the market. The friction welding process ensures the uniformity of the thickness of the pipe body through cold working of the pipe body, ensures the accuracy of the grooving drill pipes, and enhances the hardness and toughness of friction welding grooving drill pipes together. Friction welding grooving drill pipe is mainly suitable for drill bits with threaded drills. It has the characteristics of good reversal and low resistance during rotary installation. It is also relatively simple in the operation process and is liked by people. Friction welding grooved drill pipe can be welded with different materials, which improves the quality of grooved drill pipe.

Mechanical strength of auger drill pipe
In fact, the spiral drill pipe is a relatively common product, its own performance is very good, not only can drill soil, but also can be used in mine blasting. In fact, in terms of its application field, its own mechanical strength is very good. If you want to really understand the performance of the product, it is very necessary to go to its official website. In fact, everyone should know one thing, when you buy drill pipe, you must also buy its connectors, because only in this way can they be combined and used normally. Basically, each type of drill pipe corresponds to a joint and a pipe body. Basically the mechanical strength of the drill pipe

Some suggestions for reducing the wear of the drill string are worth studying!
The drill pipe is a rod connected in the drilling tool to transmit power. The drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling equipment or bottom hole device at the bottom of the drilling. The usual components of the drill pipe are: drill bit, drill collar, drill pipe, stabilizer, special joint and kelly pipe. The purpose of the drill pipe is to carry drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration, so the wear of the drill pipe is a very serious problem. When the drill pipe is worn to a certain extent, it should be replaced with a new one.
