Anti-well-buying a raise borer in the 2025 standards era

A raise borer is only as valuable as the shaft it delivers: on spec, on schedule, and inside the safety envelope defined by the latest national standard. For mining houses and underground engineering contractors planning ventilation shafts, filling shafts, chute shafts, or blind raises, the procurement question is no longer “Which raise boring machine carries the biggest torque number on the brochure?” It is whether the rig conforms to GB/T 12761-2025, which became effective on December 1, 2025, and whether the manufacturer treats anti-well (raise) drilling as an integrated system rather than a single piece of hardware. Shandong Wanli Construction Machinery Co., Ltd. answers this need with its anti-well (raise) drilling rig, listed under the company’s Raise Boring Machine category and backed by Wanli’s cross-category drilling rig engineering and direct overseas sales channel.

Why GB/T 12761-2025 Changes the Procurement Conversation

The national standard GB/T 12761-2025, titled “Raise-boring machines,” was released on May 30, 2025, and became effective on December 1, 2025, replacing the 2010 edition. Issued by the State Administration for Market Regulation and the Standardization Administration of the People’s Republic of China and administered by the National Technical Committee for Standardization of Mining Machinery (SAC/TC 88), the standard applies to raising boring rigs used in the construction of ventilation shafts, filling shafts, chute shafts, ore-pass shafts, exploratory shafts, and blind shafts in underground mines and other engineering projects.

The 2025 revision introduces substantial changes that every procurement team must understand before issuing an RFQ:

• Expanded scope: New models,, including remote-controlled drilling rigs, crawler drilling rigs, and tire self-propelled drilling rigs, are now explicitly covered
• Strengthened safety requirements: The number of safety control clauses increased from 12 to 17, with new requirements for fire extinguisher configuration, warning signs, and diesel engine exhaust emissions
• Emission limits: For diesel-engine-driven rigs, NO ≤ 900×10⁻⁶ and CO ≤ 1500×10⁻⁶
• Updated noise requirements​ and added test methods for track average ground pressure, climbing ability, tire self-propelled drilling machine braking performance, lighting, cab inspection, and diesel engine exhaust emissions
• Revised performance parameters: The standard defines type and basic parameters, working conditions, performance requirements, safety requirements, and sealing performance

For B2B buyers, the implication is direct: any raise borer quoted for a project in or after December 2025 must demonstrate conformity to GB/T 12761-2025. A supplier offering equipment built to the superseded 2010 paradigm introduces compliance and residual risk into the project.

The Anti-Well Method: Process and Engineering Discipline

Raising boring is a drilling technique used to create shafts in the mining, hydropower, and tunnel industries. The process executes in two passes:

1. Pilot hole drilling: A smaller pilot hole is drilled between two existing levels
2. Reaming pass: A reamer is mounted at the breakthrough site, then pulled upward through the rock to create the shaft

This method is safer and more predictable than drill-and-blast because it does not involve explosives. The effectiveness of the process rests on the combination of torque and thrust—the two engineering variables that define any credible raise-boring machine.

Wanli’s anti-well (raise) drilling rig is purpose-positioned for this exact two-pass process. As a member of Wanli’s Raise Boring Machine product line, the rig is offered to mining and tunnel construction clients who require GB/T 12761-2025-aligned equipment procured through a responsive, factory-direct channel.

How the Market’s Raise Borers Compare

For procurement managers, hard-parameter comparison reveals the market landscape. The following tables contrast publicly documented competitor rigs with the considerations that frame a Wanli Anti Well (raise) drilling rig procurement.

Capability Positioning Across Documented Rigs

The Wanli Anti Well (raise) drilling rig does not chase the absolute maximum envelope of a Robbins 123RH. Instead, it is positioned as a project-matched solution sourced through a factory-direct manufacturer. For mining operations that require GB/T 12761-2025 conformity, responsive manufacturer communication, and a rig configured to their specific shaft diameter and depth, Wanli’s offering occupies a strategically rational position.

Standards Compliance Framework

This table defines the procurement filter for any raise borer purchased in or after December 2025. Wanli’s Anti Well (Raise) drilling rig is offered within this framework, meaning the procurement conversation centers on how rig configuration, safety interlocks, and emission profile align with the 2025 regulatory present.

Application Scenario Mapping

GB/T 12761-2025 explicitly applies to ventilation shafts, filling shafts, chute shafts, ore-pass shafts, exploratory shafts, and blind shafts in underground mines and other engineering projects. The Wanli Anti Well (Raise) drilling rig is specified against this full range of applications, with the manufacturer configuring the rig to the project’s borehole design.

The Wanli Advantage: A Multi-Category Drilling Rig Manufacturer

What sets Wanli apart in the raise borer market is not a single maximum specification—it is the company’s position as a comprehensive drilling rig manufacturer. Wanli’s product portfolio spans:

• RC Reverse Circulation Drilling Rigs
• Vehicle-Mounted Drilling Rigs
• Down-the-Hole Drilling Rigs
• Coring Drilling Rigs
• Water Well Drilling Rigs
• Raise Boring Machines​ (including the anti-well (raise) drilling rig)

This cross-category engineering depth means that when a client procures an anti-well (raise) drilling rig from Wanli, they are working with a manufacturer that understands drilling hydraulics, mast structures, power units, and crawler mobility across multiple rig types. For mining operations that run several drilling rig categories simultaneously, this creates a single-point engineering relationship rather than fragmented supplier management.

Wanli’s direct contact channel—phone +86 13792392792, email [email protected], and physical address at New Materials Industrial Park, Yunhe Economic Development Zone, Rencheng District, Jining City, Shandong Province—means international buyers communicate directly with the factory, not through layered distributors.

The Specification Conversation: What Your Manufacturer Should Discuss

A credible raise borer supplier begins every project with engineering questions:

1. Shaft type and final diameter—ventilation, filling, chute, ore-pass, exploratory, or blind shaft per GB/T 12761-2025 scope
2. Raise length and drill angle—vertical to inclined configurations
3. Lithology—rock hardness and abrasiveness determine torque and thrust requirements
4. Mobility architecture—crawler, tire self-propelled, or remote-controlled per the 2025 standard’s expanded scope
5. Power availability—site power capacity (kVA, voltage, frequency)
6. Standard conformity—explicit alignment with GB/T 12761-2025; type inspection per Chapter 8
7. Diesel engine emission compliance—NO ≤ 900×10⁻⁶ and CO ≤ 1500×10⁻⁶ for diesel-driven rigs
8. Safety system completeness​—17 safety control clauses, fire extinguisher, warning signs
9. Test documentation—no-load test, ground pressure, climbing ability, braking, lighting, cab inspection, sealing, noise, exhaust emissions
10. After-sales and spare parts—overseas service capability for international projects

Wanli’s engineering team addresses each of these dimensions, configuring the anti-well (raise) drilling rig to the project rather than offering a take-it-or-leave-it stock unit.

Why the Manufacturer’s Total Capability Matters

When procurement teams select a raise borer, several commercial risks must be mitigated:

• Standards compliance risk—does the rig conform to GB/T 12761-2025, effective December 1, 2025? Wanli’s anti-well rig is offered within this framework
• Configuration risk—can the manufacturer configure the rig to project-specific shaft diameter, depth, and lithology? Wanli’s project-matched approach answers this directly
• Capacity risk—can the manufacturer deliver the rig on schedule? Wanli operates as a comprehensive drilling rig manufacturer with extensive product lines
• Communication risk—can the buyer reach the factory directly? Wanli provides direct phone, email, and address
• Lifecycle risk—does the procurement align with the 17 safety requirements, updated noise thresholds, and emission limits of the 2025 standard?

GB/T 12761-2025 reminds the industry that the technological evolution of raising boring rigs now explicitly encompasses remote-controlled drilling rigs, crawler drilling rigs, and tire self-propelled drilling rigs—the 2010 edition did not. A supplier that designs to this expanded paradigm and validates performance through the standard’s specified test methods becomes a true engineering partner for the next decade of shaft construction.
