矿井顶板事故分析研究及预防机制

Research on Accident Prevention Mechanism of Mine Roof

新驿煤矿建矿以来发生数次顶板事故,给矿井安全生产带来了极大压力,造成财力物力浪费,工程进度减慢,周期变长,经济效益降低。通过研究分析发现顶板事故跟地质条件、巷道开门位置、跨度、顶板支护参数选择等方面有着密切的联系,根据事故原因采取相对应的措施,结合矿井近年来顶板管理经验,很好地预防了顶板事故发生。

Since the construction of Xinyi Coal Mine, there have been several roof accidents, which have brought great pressure to mine safety production, caused waste of financial and material resources, slowed down the progress of the project, prolonged the period and reduced the economic benefits. Through research and analysis, it is found that roof accidents are closely related to geological conditions, roadway opening position, span, roof support parameter selection, etc. According to the causes of the accidents, corresponding measures are taken, combined with the experience of roof management in recent years, which can prevent the occurrence of roof accidents.
