LGMRT SDC150H Down-the-hole Drill Rig Field Report from Xinjiang Mine Site

In the vast and magnificent Naomaohu mining area in Xinjiang, a mega coal mine with an annual production of 35 million tons is operating in an orderly manner. The Naomaohu mining area boasts more than 64 billion tons of high-oil coal reserves, with an average oil content of 12%, capable of producing high value-added products such as coal tar and coal gas. The extreme climate here is the ultimate test of equipment performance and reliability—scorching summers, freezing winters, and dramatic temperature differences between day and night.

On this challenging land, the newly launched LGMRT SDC150H down-the-hole drill rig has quickly earned customer recognition with its outstanding performance, writing its own chapter of proven strength.

Trust Begins with Choice

From Trial to Continuous Repeat Purchases

The story between the SDC150H and Baishihu mining area began in April 2025, when the first SDC150H arrived at the site for trial operation. After more than 1,000 hours of intensive work, its stable availability and excellent economic performance won over the customer, eventually achieving a successful “trial-to-purchase” conversion.

Market validation is the strongest proof. Thanks to the remarkable performance of the first machine, the mining area continued to purchase multiple SDC150H units between August and October. From a single trial machine to multiple repeat purchases, the SDC150H demonstrated its strong market competitiveness in just a few months.

Numbers Speak Louder

A “Thinking” Fuel-saving Philosophy

In mining operations, efficiency and cost are eternal priorities. Designed for a 152 mm hole diameter, the SDC150H fully meets the drilling efficiency needs of large-scale mines while significantly optimizing production costs.

What satisfies customers most is its impressive fuel-saving performance. Equipped with an intelligent load-sensing hydraulic system and a CMS compressor management system, the SDC150H accurately matches power output, greatly reducing fuel consumption. On-site data shows that this model saves about 10% in fuel consumption. Based on 3,000 annual operating hours, a single machine can save tens of thousands of yuan in fuel costs each year—making its long-term cost performance increasingly prominent.

Unafraid of Harsh Conditions

Hard-core Configuration Built for Extreme Environments

At Naomaohu Mine in Xinjiang—where summers are scorching, winters are freezing, and wind and sand are relentless—the SDC150H has demonstrated exceptional reliability with its comprehensive adaptability configuration.

Stable Performance in High Temperature and Dust
To withstand extreme summer heat and continuous sandstorms, the SDC150H comes equipped with a desert air filtration system that serves as the engine’s “first line of defense.” After 1,900 hours of continuous operation in heavy-dust conditions, inspections showed that the engine remained clean, proving the filtration system’s effectiveness. From June to September, when temperatures reached up to 50°C, the machine ran smoothly with zero heat-related failures—showcasing its excellent heat resistance.

Fearless in Extreme Cold—Reliable Starts Every Time
To tackle winter temperatures as low as –35°C, the SDC150H is equipped with a special cold-weather package and preheating system to ensure smooth low-temperature starting and enhance continuous operation capability. The 600L main fuel tank (0# diesel) + 22L auxiliary tank (–35# diesel) design allows customers to use standard diesel in winter, significantly reducing costs.

Upgraded Structure Ensures High Availability
Compared with the SDC150, the SDC150H features a drilling boom extended to 3.5 m, enabling the drilling of two holes in one positioning (3.5 m spacing). Key structural components—such as the drill boom, chassis, and feed beam—have been reinforced with thicker plates and high-strength structural steel. This results in a 35% improvement in machine strength and low-temperature resistance, significantly reducing failure rates. During batch operation of multiple machines, the SDC150H consistently maintained high availability, fully meeting the demanding uptime requirements of coal mining operations.

Dedicated On-site Support

A Strong Shield for Customer Value

Excellent equipment must be paired with dependable service. LGMRT has established a service station and spare parts warehouse within the mining area, ensuring fast response and timely parts supply whenever needed—maximizing machine availability and continuously creating value for customers.

Continuous Improvement

Listening to the Market, Co-creating the Future

While receiving strong market recognition, LGMRT remains open-minded and values feedback from every user. Based on customers’ suggestions regarding cab comfort and maintenance accessibility, the R&D team has already begun optimizing these areas for future product iterations, striving to deliver equipment with stronger performance and a better user experience.

With its distinctive features—high efficiency, fuel savings, reliability, and strong adaptability—the LGMRT SDC150H down-the-hole drill rig is steadily gaining ground in China’s core mining markets. Its story has only just begun, and in the future, it will continue to stand alongside customers, enduring the Gobi’s wind and cold, becoming their most trusted partner in creating value.
