In a significant advancement for the coal mining sector, researchers have unveiled key technologies and equipment aimed at enhancing the efficiency of fully mechanized mining in super high and super long working faces. This research, led by Mingzhong Li from Beijing Tianma Intelligent Control Technology Co., Ltd., highlights the pressing need for innovative solutions in a field that remains critical to China’s energy landscape.
With coal continuing to play a vital role in China’s economic growth, the demand for safe and efficient mining practices has never been more urgent. Li notes, “Our research focuses on achieving a reliable and green mining process, especially in areas with thick and medium-thick coal seams.” The study outlines how certain mines in China have already achieved remarkable outputs, with some reporting single-well single-side outputs exceeding 10 million tons.
The research draws from a national key research and development project that explores the complexities of mining in expansive geological settings. It addresses three major scientific issues that impact the stability and efficiency of mining operations: the dynamic fracture laws of overburden rock, the structural transformation of strong overburden rock, and the operational dynamics of mining equipment under various loads.
Five technical breakthroughs were identified, including advanced fracturing and pressure relief technologies, which are crucial for managing the intense conditions often found in super-large mining spaces. The innovations also encompass intelligent mining equipment designed to work collaboratively, enhancing both safety and productivity.
The implications of this research extend beyond immediate operational benefits. By developing a comprehensive technology and equipment system tailored for ultra-high and ultra-long coal mining faces, the construction sector stands to gain significantly. Improved mining practices can lead to increased coal availability, supporting infrastructure projects and energy needs across the nation.
Li emphasizes the potential for these advancements: “As we refine these technologies, we not only enhance mining efficiency but also contribute to a more sustainable energy future for China.” This holistic approach to mining technology could pave the way for a new era in resource extraction, balancing economic demands with environmental considerations.
The findings were published in ‘Meitan kexue jishu’, which translates to ‘Journal of Coal Science and Technology’, underscoring the research’s relevance to ongoing discussions in the industry.
