我国煤矿冲击地压的现状、问题与思考

Current situation and reflective analysis of coal-bump problems in China’s coal mines

  • 摘要: 近10年来,我国冲击地压防控事业成效显著,科学防冲理念已深入人心,成体系的政策制度与技术方案为煤炭资源开发筑牢了安全屏障。然而,随着煤矿开采深度不断增加、开采强度持续提升,全国冲击地压矿井数量已达177座(不完全统计),且呈逐年上升趋势。与此同时,矿井产能“整体西移”至“晋−陕−蒙−新”核心产煤基地,“单矿集中”的现代化矿井模式让防冲工作面临全新挑战,缺乏现成经验可借鉴,冲击地压已成为制约这些区域产能科学合理释放的关键因素。当前,煤矿深部开采与千万吨级产能的工程背景,大幅压缩了防冲工作的容错空间与试错机会,传统“经验尝试、先干后调”的模式已无法应对现有挑战,尤其是地面压裂、井下超长孔等覆盖大范围采掘空间的区域性措施,对差异化与精准化的要求达到了新高度。尽管行业内已公认从源头实现冲击地压有效防控是最优路径,但如何将这一理念转化为可执行、能落地的科学理论、工程技术与专用装备,仍缺乏清晰解决方案。值得关注的是,近年来数字化、智能化技术的飞速发展,为冲击地压防控带来了新机遇,数字化源头防控等全新技术范式呼之欲出。在此承前启后的关键时期,系统梳理我国冲击地压的现状与问题,深入解析核心矛盾,不仅能为煤炭行业高质量发展提供必要的认知基础,更能为构建精准化、数字化的防冲体系提供方法论支撑。

     

    Abstract: Over the past decade, China has achieved remarkable progress in the prevention and control of coal bursts. The scientific philosophy of burst prevention has taken root, and a coherent body of policies, regulations and technical solutions has erected a solid safety barrier for coal-resource development. However, as coal mining depths continue to increase and extraction intensity keeps rising, the number of rock burst mines across the country has reached 177 (based on incomplete statistics), showing a year-on-year upward trend. At the same time, coal production capacity has been shifting westward to the core mining bases of "Shanxi-Shaanxi-Inner Mongolia-Xinjiang". The modern mining model characterized by "concentrated single-mine operations" presents new challenges for rock burst prevention, with no ready-made experience to draw from. Rock burst has become a critical factor restricting the scientific and rational release of production capacity in these regions. Currently, the engineering context of deep mining and ten-million-ton production capacity in coal mines has significantly reduced the margin for error and opportunities for trial-and-error in rock burst prevention. The traditional approach of "experience-based trials and adjustments after implementation" can no longer address the existing challenges. In particular, regional measures covering large-scale mining areas, such as surface fracturing and ultra-long boreholes underground, now demand unprecedented levels of differentiation and precision. Although the industry agrees that effective burst prevention must start at the source, turning this consensus into executable scientific theory, engineering technology and dedicated equipment remains an unresolved issue. Worth noting is that the rapid advance of digital and intelligent technologies in recent years has opened new windows of opportunity; a novel paradigm of digital source prevention is emerging. At this hinge moment, a systematic review of China’s coal-burst status and problems—and an in-depth analysis of the core contradictions—will not only furnish the cognitive foundation required for high-quality development of the coal sector, but also provide methodological support for building a precise, digital burst-prevention system.
