KAMY CHINA Gob Filling Equipment: Leading a New Era in Coal Gangue Disposal and Green Mining
Coal gangue disposal has long been a critical challenge in coal mining operations. Piled high, this waste not only consumes valuable land resources but also poses significant environmental risks, such as water contamination during rain and safety hazards in dry conditions. Additionally, the processes of loading, transporting, crushing, and managing gangue dumps incur substantial human and financial costs.
In response to these challenges, KAMY CHINA, a leading supplier of gob filling equipment, has partnered with Huangling Mining Shuanglong Coal Mine to pioneer an innovative solution for coal gangue disposal.
Tackling the Challenge
Shuanglong Coal Mine previously faced the pressing issue of handling over 70,000 cubic meters of coal gangue. Traditional surface disposal would have resulted in the formation of a massive gangue dump, with potential leachate and safety concerns. Moreover, such methods hindered the mine’s efforts toward low-carbon, energy-efficient, and environmentally sustainable development.
KAMY CHINA’s Comprehensive Solution
To address the issue, KAMY CHINA aligned with the national strategy of intelligent mining and introduced a revolutionary concept: underground roadway backfilling. Since the implementation of coal gangue backfilling in July 2022, the mine has undergone a remarkable transformation. The once noisy, dust-filled site dominated by transport vehicles and crushing machines has been replaced with a clean, green, and modern garden-style mining area.
Advanced Engineering:
KAMY CHINA’s gob filling equipment adopts a “2+2” construction model—four continuous backfilling roadways, including one active backfilling section, one standby, and two under construction. The process is optimized through phased operations and adaptive construction methods tailored to complex geological conditions, significantly improving efficiency and overcoming site-specific challenges.
Safety Assurance:
Safety remains paramount. During the backfilling process, KAMY CHINA assisted Shuanglong Coal Mine in implementing a dual-prevention safety system, encompassing risk management and hazard rectification. Each active face was sealed off for targeted inspections and timely rectification measures, ensuring secure and stable operations throughout the filling process.
Intelligent Equipment:
The gob filling system supplied by KAMY CHINA integrates automatic crushing and remote operation. Smart devices such as the TCJ-D80/30/67 gob filling equipment and ZWY-120/55L excavating loader are characterized by reliable performance, user-friendly controls, and low maintenance costs—providing robust hardware support for intelligent, large-scale backfilling operations.
Professional Training:
To ensure optimal equipment performance and operational efficiency, KAMY CHINA also delivered specialized training services. Shuanglong Coal Mine complements this by organizing no fewer than four technical training sessions annually, involving classroom learning and expert-led instruction. These sessions focus on equipment operation, maintenance, troubleshooting, and the design and construction of gangue backfilling roadways. As of now, over 20 young professionals have emerged as key members of the gangue backfilling initiative.
Remarkable Results
By the end of 2024, Shuanglong Coal Mine had successfully backfilled 70,000 cubic meters of coal gangue, fully realizing the principle of “returning what is taken from nature back to nature.” This achievement has not only resolved a longstanding ecological challenge but also propelled the company toward high-efficiency and environmentally responsible growth.
As a leading provider of gob filling equipment, KAMY CHINA remains committed to technological innovation and service excellence, striving to deliver efficient and sustainable coal gangue disposal solutions to mining enterprises worldwide—contributing to the green transformation of the industry.
