Smarter Raise Boring for 2026 Shaft Projects

Raising boring is only as dependable as the rig behind it and the standard it is built to. For mining houses and underground engineering contractors planning ventilation shafts, filling shafts, chute shafts, ore-pass shafts, exploratory shafts, or blind shafts, the procurement question in 2026 is no longer simply about which raise boring machine carries the biggest torque number in its brochure. It is whether the rig conforms to GB/T 12761-2025, the national standard for raise-boring machines that came into effect on December 1, 2025, and whether the supplier treats raise-boring as an engineered system rather than a single piece of hardware. Shandong Wanli Construction Machinery Co., Ltd. answers this need with its Hydraulic Raise Borer, offered through Wanli’s direct factory channel and configured to project-specific shaft requirements.

Why GB/T 12761-2025 Redefines the Raise Boring Conversation

The national standard GB/T 12761-2025​ was released on May 30, 2025, and came into effect on December 1, 2025, completely 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 raise-boring machines 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 absorb before issuing an RFQ:

• Expanded product 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
• New mandatory provisions: 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 nine newly added test methods: track average ground pressure, climbing ability, braking performance, lighting, cab inspection, noise, and diesel engine exhaust emissions
• Changed technical parameters: Type and basic parameters, environmental adaptability, and maximum thrust/pull test methods were all revised

For B2B buyers, the implication is direct: any raise boring rig 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 Raise Boring Process: Engineering Discipline Over Marketing Claims

Raising boring is a well-established method for creating shafts in the mining, hydropower, and tunnel industries. The process executes in two passes:

1. Pilot hole drilling: A small-diameter pilot hole is drilled from the upper level down to the lower level
2. Upward reaming: After breakthrough, a large reaming head is attached at the bottom and pulled upward as it cuts the rock

Epiroc—whose Robbins rigs have set the industry benchmark for more than fifty years—explains that this method creates smooth-walled raises typically used for ventilation, ore passes, service shafts, and escape ways. 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 Hydraulic Raise Borer is purpose-positioned for exactly this two-pass process. As a full-hydraulic raise boring machine configured to project-specific parameters, it is offered to mining and tunnel construction clients who require GB/T 12761-2025-aligned equipment sourced through a responsive, factory-direct channel.

How the Market’s Raised Boring Rigs 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 Hydraulic Raise Borer procurement.

Capability Positioning Across Documented Rigs

The Wanli Hydraulic Raise Borer does not chase the absolute maximum envelope of an Epiroc Robbins 92R or 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 boring rig purchased in or after December 2025. Wanli’s Hydraulic Raise Borer 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 Hydraulic Raise Borer is specified against this full range of applications, with the manufacturer configuring the rig to the project’s borehole design, rock conditions, and site power availability.

The Wanli Advantage: A Multi-Category Drilling Rig Manufacturer

What sets Wanli apart in the rising boring 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
• Hydraulic Raise Borer​ (including the Anti Well series)

This cross-category engineering depth means that when a client procures a hydraulic raise borer 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, boring 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 (typically 45°-90° from horizontal)
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 hydraulic raise borer 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 boring rig, several commercial risks must be mitigated:

• Standards compliance risk—does the rig conform to GB/T 12761-2025, effective December 1, 2025? Wanli’s Hydraulic Raise Borer 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 raise-boring machines 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.
