煤矿安全一直是我国的一个突出问题，它不仅影响煤炭企业自身的生存与发展，而且制约着国民经济的发展。它不仅是煤炭企业的自身问题，而且是一个严重的社会问题。这几年，随着社会经济的发展需求，我国煤炭产量大幅度增加。然而随着煤炭产量的增加，煤矿伤亡事故也连连发生，给社会带来了严重的不良影响，给人们的生命、财产造成了不可估计的损失。 本文从安全管理学、质量管理学等基本理论出发，用概率论、统计学等数学方法，对宁煤集团灵新煤矿10年来发生的各类事故进行分析，在总结灵新煤矿成功经验的同时，经过分析、提炼，找出灵新煤矿安全管理中存在的主要问题。通过对10年来发生的事故类型和形成因素的统计、分析，认为：灵新煤矿的安全隐患仍然主要是管理方面的问题。本文系统研究了煤矿安全的PDCA管理模式，提出了适合灵新矿的PPDCA安全管理模式，通过“计划—预防—执行—检查—整改”五个阶段的循环，从灵新矿安全管理的源头做起，延伸到安全管理的每个角落，大循环带小循环，阶梯式上升，实现安全管理体系的持续改进和可持续发展，有效的分析和掌握矿井的生产过程中所出现的安全管理问题，将会对灵新矿的安全管理工作起到一定的促进作用。

Mine safety is the most serious issue for the coal industry, which affects the healthy development of the industry and the growth of the economy. Mine safety is not only concerned by coal enterprises, but also becomes a big issue for the whole society. For the recent years, coal production in China has been increasing consistently while the death toll due to accidents in the coal industry has been sustaining at a high level, thus putting a seriou impact on the industry and the society. Based on theories of safety management, quality control and the so forth, accidents in the last 10 years in Lingxin Coal Mine are analysed with suitable mathematical methods. Valuable experiences of safety management in lingxin Mine are summarized, the existing shortcomings are discussed, and the accidents of the last 10 years are classified according to their type and cause.To the writer’s opinions, the potential risks in mine safety in Lingxin Mine are real and the key countermeasures rely on its safety management. The PDCA management pattern in mine safety control in Lingxin Coal Mine is systematically studied and being further expanded to PPDCA cycle, i.e. the management cycle composed of “Plan-Prevent-Do-Check-Action” five steps. The PPDCA cycle of safety management conducts the every step in the process of mine production to gain progress in sparals in its safety control, thus achieving a consistent improvement and sustainable development for the mine. The achievements in the analysis of safety management in Lingxin Coal Mine are important and will facilitate the development of the mine in the futher.
