The rock reamer hole opener is a device used for expanding rock holes. Comprehensive consideration should be taken into account when selecting a rock reamer opener. This article will provide you with a detailed introduction.
Rock reamer hole opener consists of the main body, tools, and expansion device. The main body is the supporting frame of the entire equipment, which requires good rigidity and light weight for easy carrying. The tools are used for cutting rocks, requiring wear resistance and impact resistance. The expansion device is used to enlarge rock holes, requiring a simple structure and easy operation.
When choosing a rock reamer hole opener, first clarify the usage purpose and select the appropriate specifications and models based on actual conditions. Secondly, choose a reliable manufacturer, understand their production history and user reviews to ensure product quality. Also, pay attention to the weight and price of the equipment for easy transport and use. Lastly, focus on the operational performance of the equipment, particularly whether the expansion device is convenient and reliable to operate. In addition, consider the following factors:
Drilling speed and efficiency
Selecting the appropriate reamer can significantly increase drilling speed and reduce construction time.
Equipment failure rate
An unsuitable rock reamer hole opener may increase the equipment failure rate, affecting construction progress and costs.
Hole wall stability
Maintaining wall stability is key to ensuring smooth drilling operations.
It can quickly expand rock holes, improving construction efficiency;
It can effectively protect the safety of construction personnel, preventing injuries caused by factors such as explosions;
It can reduce construction costs and minimize wear and tear on machinery;
It has characteristics such as simple structure, easy operation, lightweight, and portability.
Rock reamer hole openers are suitable for various types of rocks, and the choice mainly depends on the hardness and wear resistance of the rock. The following is an overview of different types of rocks and their suitable reamers:
High compressive strength rocks
Such as sandstone, limestone, dolomite, gypsum, marble, etc. These rocks have high compressive strength, so it is necessary to choose reamers that can efficiently cut and maintain wall stability. For example, multi-wheel rock reamer hole openers (such as 3-wheel, 4-wheel, or more) and diamond bits are common choices as they can handle the hardness and wear resistance of these rocks.
Hard and highly abrasive formations
When drilling these formations, it is advisable to choose purely rolling cone bits and double cone bits. These bit designs help maintain efficient drilling in hard rocks.
Soft rocks
Such as some limestones and sandstones. Although these rocks have relatively low hardness, choosing a suitable hole opener reamer is still important to ensure drilling efficiency and wall stability. Conventional reamers, especially those with appropriate support structures, are suitable for these rocks.
Fractured or loose formations
When drilling in these layers, special designed rock reamer hole openers should be selected, such as those with stronger support structures to prevent wall collapse.
Horizontal directional drilling rock formations
In horizontal directional drilling, common rock reamer hole openers include conventional reamers and tungsten carbide reamers. Conventional reamers are suitable for rocks of general hardness, whereas tungsten carbide reamers, due to their high hardness material, are more suitable for harder rock formations, offering better cleaning effects and longer service life.
Mining
In mining, rock reamer hole openers can be used to quickly expand rock holes, improving mining efficiency.
Underground engineering
In underground construction, rock reamer hole openers can be used to expand rock holes, increasing construction efficiency.
Emergency rescue
In emergency rescues, rock reamer hole openers can be used to quickly expand rock, rescuing trapped personnel.
