What is rock drilling machinery?
Rock drilling machinery is a professional equipment used to break rocks in mining, tunnels, construction and other projects. It is widely used in infrastructure construction, resource extraction and other fields. With the development of technology, modern rock drilling machinery has developed from traditional manual operation to automated and intelligent equipment, which has greatly improved construction efficiency and safety. This article will combine the hot topics on the Internet in the past 10 days to analyze the definition, classification, application and market trends of rock drilling machinery.
1. Definition and classification of rock drilling machinery
Rock drilling machinery is mechanical equipment that breaks rock through impact, rotation or cutting. It is mainly divided into the following categories:
| type | Working principle | Typical equipment |
|---|---|---|
| Impact rock drill | Breaking rocks through high-frequency impact | Pneumatic rock drill, hydraulic rock drill |
| Rotary rock drill | Cutting rock by rotating drill bit | Rotary drilling rigs, tunnel boring machines |
| Compound rock drill | Combined impact and rotation | Multifunctional drilling rig, intelligent rock drilling rig |
2. Application fields of rock drilling machinery
Rock drilling machinery plays a key role in several fields:
| Application areas | Specific use | Popular cases (last 10 days) |
|---|---|---|
| Mining | Ore blast hole drilling and tunnel excavation | A certain lithium mine project introduced intelligent rock drilling rigs, increasing efficiency by 40% |
| tunnel engineering | Railway and highway tunnel excavation | Sichuan-Tibet Railway Tunnel uses hydraulic rock drill to break through hard rock layer |
| building construction | Foundation treatment, rock crushing | A construction site in Shenzhen uses environmentally friendly rock drilling equipment to reduce dust |
3. Recent popular technologies and market trends
According to the analysis of the entire network data in the past 10 days, the hot spots in the field of rock drilling machinery are concentrated in the following directions:
| hotspot direction | Content summary | Data/Case |
