Rock Blasting Drill Working for Mining Work

June 13 , 2024

Drilling and blasting has always been the main construction method for rock excavation of underground and surface buildings. This way has strong adaptability to rock geological conditions and low excavation cost, and is particularly suitable for cavern construction with hard rock. When excavating underground buildings by drilling and blasting, blasting design should be made according to design requirements, geological conditions, blasting materials and drilling equipment. The main tasks of drilling and blasting design are: ① Determine the arrangement of blast-holes in the excavation section, including the location, depth and direction of various blast-holes; ② Determine the charge, charge structure and plugging method of various blast-holes; ③ Determine the detonation method and detonation sequence of various blast-holes. Compared with open-pit excavation blasting, underground cavern rock excavation and blasting construction has the following main characteristics: (1) Due to the influence of lighting, ventilation, noise and water seepage, the drilling and blasting working conditions are poor; the drilling and blasting work is carried out in conjunction with support, slag transportation and other processes, which limits the construction site and increases the difficulty of construction. (2) There are few free blasting surfaces, and the clamping effect of rocks is large, which increases the difficulty...

The working principle of water well drilling rig machine.

May 31 , 2024

The UY series water well drilling rig is full hydraulic open-hole drilling equipment. It is powered by a diesel engine. By driving a hydraulic oil pump to form a high-pressure oil circuit, the hydraulic pressure is driven by manipulating various relevant hydraulic control valves on the console. The motor and hydraulic cylinder performs various predetermined actions. The power is activated during operation, pushing the handle of the rotary control valve on the console, and the pressure oil is driven by the rotary motor on the rotary motor. Push the handle on the walking control valve to realize the forward, backward, and turn movement of the whole machine. Push the handle on the console to control the movement of each relevant cylinder and hoisting motor, and complete the telescopic movement of the guide rail and the unloading cylinder, the leg cylinder, the telescopic cylinder, and the coil The forward and reverse movement.

Maintenance measures for drilling equipment

April 23 , 2024

Broadly speaking, drilling equipment includes complete sets of surface equipment, special drilling tools and drilling instruments used for drilling. According to the function, it can be divided into rotation, lifting, circulation, power and transmission, control and other systems. Equipment will inevitably experience some minor wear and tear after constant use. Therefore, we must take maintenance measures. Drilling engineering 1. Do a good job in classification and organization In the process of maintenance of drilling equipment, we must do a good job in classification and organization. Comprehensively organize the spare parts of the equipment. During the maintenance process of the equipment, there will definitely be relatively many parts used, so we must comprehensively organize the overall parts to achieve the ideal arrangement. Effect. Information on maintenance mechanisms should also be collated. Let the equipment maintenance achieve the best results. 2. Check the pipeline connections of the equipment In the process of maintenance of drilling machinery and equipment, we need to conduct a comprehensive inspection of the pipeline connections of the equipment. Under normal circumstances, there will be no cracks in the equipment’s pipelines, but under high-intensity operations, equipment failures often occur in the connections. Therefore, during the maintenance process, relevant personnel...

How to choose a down-the-hole drilling rig?

April 13 , 2024

1. Choose according to your needs At present, down-the-hole drilling rigs are used very frequently and have many uses. Drilling machinery is divided into two categories: rock drills and drilling rigs. The functions, prices, and power consumption of down-the-hole drilling rigs for each purpose are different, so when we choose down-the-hole drilling rigs, Choose the corresponding equipment according to your own needs and uses. Good equipment allows us to better complete the project and gain recognition from customers. 2. Simple and convenient operation Operating a down-the-hole drilling rig requires certain skills, and it also tests the driver’s ability. Currently, there are a variety of down-the-hole drilling rigs developed, and their functions are even more confusing. Therefore, when we choose a product, we should also pay attention to whether the operation is complicated, whether it is difficult to get started, and the level of safety protection factor. 3. High value retention rate After a project is completed, down-the-hole drilling rigs are often left idle and prone to rust. This is when we don’t need it, we can sell it to the second-hand market for asset preservation. However, because of the low market acceptance of some no-name phones, the price of second-hand...

How to choose the right water well drilling rig?

March 27 , 2024

When selecting a suitable water well drilling rig, simple configuration, low energy consumption, easy operation, high maneuverability, high versatility and small size are usually required. In actual operation, the appropriate drilling rig type needs to be selected based on factors such as formation conditions, borehole size, drilling depth, and drilling methods. 1. Drilling efficiency: Drilling efficiency is affected by many factors such as formation conditions, operator skills/experience, drilling rig type and drilling methods. When rock conditions are applicable, it is recommended to use an underground drilling rig with an air compressor; for soil, clay and sand conditions, the best option is to use a drilling rig with a mud pump; while in conditions such as cobblestone, a reverse circulation system is the most suitable drilling method . 2. Price: The price of the machine is a key factor in choosing a suitable drilling rig, and it is also a one-time investment. As the borehole diameter and depth increase, so does the machine price. Comparing different drilling rig types, the price of down-the-hole drilling rigs is higher than that of core drilling rigs, and the price of hydraulic drilling rigs is higher than that of vertical shaft drilling rigs. In addition,...
