The 28th CHINA MINING Conference and Exhibition 2026 was held from September 10 to 12, 2026, at the Tianjin Meijiang Convention and Exhibition Center in Tianjin, China.

As one of the major international mining events held in China, CHINA MINING brings together people from across the mining industry. That includes mining companies, geological exploration groups, equipment makers, technology providers, investors and industry experts.

The theme of CHINA MINING 2026 was: “Win-Win Cooperation, Green and Intelligent Mining.”

For Chenghui, events like CHINA MINING give us an important chance to see how drilling technology is changing and how drilling-tool makers can support ever harder exploration and mining work.

A Global Platform for the Mining Industry

Modern mining projects are becoming more demanding. Exploration depths are growing. Geology is getting more complex. Mining companies are putting more weight on:

• Drilling efficiency
• Tool life
• Cost per meter
• Energy use
• Environment
• Automation
• Smart mining
• Reliable supply chains

CHINA MINING 2026 shows these shifts by bringing together companies and experts from different parts of the mining chain. Public reports on the 2026 event describe broad attendance, with talks focused on global teamwork, investment, green mining and smart mining tech.

For drilling-tool makers, these changes bring both chances and new technical needs.

Drilling Tools Remain at the Beginning of Every Exploration Project

Before a mine can be built, the geology must first be understood. That needs drilling. Whether the goal is:

• Mineral exploration
• Geological study
• Rock sampling
• Borehole work
• Mine water checks
• Gas drainage
• Grouting
• Production drilling

the drill bit is one of the first tools to touch the rock. Its performance can shape:

Penetration Rate + Borehole Quality + Core Recovery + Bit Change Frequency + Rig Downtime + Total Drilling Cost

Because of this, bit choice remains a key part of mining project economics.

Chenghui’s Drilling Solutions for Mining and Geological Exploration

Chenghui focuses on drilling tools for a wide range of geological and engineering jobs. Our product family covers several major groups.

Brocas PDC

PDC tools work in suitable rock where steady shearing can give fast rock removal. Our PDC range includes:

• Flat-top PDC bits
• Concave PDC bits
• Arc PDC bits
• Spiral PDC bits
• PDC drag bits
• PDC core bits
• Custom PDC drill bits

Depending on the drilling conditions, cutting structures can be adjusted through:

• Blade number
• Cutter size
• Cutter count
• Cutter layout
• Bit profile
• Gauge protection
• Waterway setup

For mining work, the right PDC setup should always be picked by rock strength, abrasiveness and fracture state.

PDC Core Bits for Geological Exploration

Mineral exploration often needs more than just a hole. Geologists may need real core samples to check:

• Lithology
• Mineralization
• Formation edges
• Fractures
• Structure
• Rock quality

PDC core bits can give fast coring in selected soft-to-medium and solid rock. Different cutter setups can be made to match:

• Outside diameter
• Core diameter
• Rock type
• Core barrel
• Drilling depth
• Flushing

For harder and more abrasive rock, diamond core systems may suit better.

Diamond Core Drilling Tools

Diamond core drilling is still one of the most important methods in mineral exploration. We supply core drilling products for common geological systems, including:

AQ · BQ · NQ · HQ · PQ · NTW · HTW

Products can include:

• Impregnated diamond core bits
• Electroplated diamond bits
• Reaming shells
• Wireline core drilling tools
• Other core drilling parts

The right diamond bit should be picked by rock hardness, abrasiveness and the core recovery needed.

Tricone Drill Bits for Mining Applications

Tricone bits stay important in many mining and exploration jobs. Unlike fixed-cutter PDC bits, tricone bits use rotating cones to break rock through:

• Crushing
• Indentation
• Scraping

Our tricone range includes:

• TCI tricone bits
• Steel-tooth tricone bits
• Roller cutters

Different structures can be picked by the expected rock. For fractured, mixed or impact-heavy rock, a well-picked tricone bit may sometimes suit better than a PDC bit. In short, professional bit choice should always start with geology.

DTH Drilling Tools for Hard Rock

Hard-rock mining often needs percussive drilling. DTH systems send impact energy right to the bit at the bottom of the hole. This makes them very effective in many solid hard-rock formations.

Our DTH range includes:

• DTH hammers
• DTH drill bits
• DTH accessories

DTH systems are often used for hard crystalline rock, mining, quarrying and water wells.

Why Formation Matching Is Becoming More Important

One key trend across the mining industry is more attention to overall drilling efficiency. The cheapest bit is not always the most economical drilling answer.

A more useful question is: how much does it cost to finish each meter of drilling?

That sum may include:

• Bit price
• Bit life
• Average penetration rate
• Number of bit changes
• Rig downtime
• Energy use
• Labor
• Drilling fluid
• Tool upkeep

A tool that costs more up front may still lower total project cost if it drills more meters and cuts needless trips. This matters even more in deep mineral exploration.

Customization for Different Mining Projects

Mining projects rarely use the same drilling conditions. Even two projects drilling the same rock type may face different:

• Strength
• Abrasiveness
• Fracturing
• Depth
• Borehole diameter
• Rig capacity

Because of this, we support custom drilling-tool solutions. Depending on the product, changes can include:

• Diameter
• Cutter spec
• Blade count
• Cutter layout
• Gauge structure
• Waterways
• Connection
• Body sizes
• Wear protection

Customers can send us:

• Technical drawings
• Existing drill bits
• Used-bit photos
• Rock photos
• Core samples
• Rig specs

In short, these details help us see the real drilling conditions.

Used Drill Bits Can Tell Us What Happened Underground

One of the most useful sources of drilling data is the used bit. Wear patterns can help spot possible problems.

For customers facing drilling problems, photos of a used bit can sometimes help more than a simple rock description.

Green and Intelligent Mining Also Means More Efficient Drilling

The theme of CHINA MINING 2026 — “Win-Win Cooperation, Green and Intelligent Mining” — shows a wider trend in the mining industry. For drilling work, better efficiency fits this direction.

A drilling tool that:

• Lasts longer
• Needs fewer changes
• Keeps steady penetration
• Cuts needless rig time
• Improves drilling consistency

can help reduce resource and energy use across a project. Because of this, drilling-tool work should focus not only on tool life, but also on how the full drilling system performs.

Connecting Chinese Manufacturing With International Mining Projects

CHINA MINING has long served as a meeting point between China’s mining industry and the global market. The 2026 event again brought global mining people to Tianjin. Public reports describe companies and groups from several countries attending to look at tech, investment and teamwork chances.

For Chenghui, global teamwork is also a key part of our growth. Different markets bring different drilling challenges. Customers may need tools for:

• African water-well and mining projects
• Russian geological exploration
• Middle East drilling
• Southeast Asian water-well projects
• South American mining and exploration
• Other global engineering work

Seeing these different drilling conditions helps us keep improving our product range.

More Than Selling a Drill Bit

Professional drilling-tool teamwork should not end when the product is shipped. Customers may need help to work out:

• Which drill bit to use
• Which cutter setup fits
• What connection is needed
• Whether PDC, tricone, diamond or DTH fits better
• Why a past bit failed
• How the next design can improve

This technical talk matters most for custom products. Our goal is to move from simply supplying bits toward giving more practical, formation-matched drilling solutions.

Looking Ahead After CHINA MINING 2026

CHINA MINING 2026 once again showed the steady growth of global mining teamwork, green mining and smart mining tech. For drilling-tool makers, the direction is just as clear.

Future drilling tools need to deliver:

• Greater consistency
• Better wear resistance
• More accurate formation matching
• Improved drilling efficiency
• Lower cost per meter

Chenghui will keep developing and improving PDC bits, core drilling tools, tricone bits, DTH tools and custom drilling solutions for mining and geological exploration projects.

We look forward to sharing ideas with customers, drilling contractors and mining experts from around the world.
