Roof bolting typically follows the extraction of a commodity to help keep the roof from collapsing. During 2004 to 2013, roof bolter operators had the highest number of machinery-related injuries, accounting for 64.7 percent, at underground coal mines. This paper analyzes U.S. roof bolter fatal and nonfatal lost-time injury data at underground work locations for all commodities from 2004 through 2013 and determines risk indices for six roof bolting tasks. For fatal and nonfatal incidences combined, the roof bolting tasks in order of the highest to lowest risk index were bolting, handling of materials, setting the temporary roof support (TRS), drilling, tramming, and traversing. For fatalities, the roof bolting tasks in order of the highest to lowest risk index were handling of materials, setting the TRS, bolting, drilling, traversing, and tramming. Age was found to be a significant factor. Severity of injury, indicated by days lost, was found to increase with increasing age as well as with increasing experience, largely due to the confounding of age and experience. The operation of the roof bolting machine used in underground mining should be a research priority given the high frequency and severity of incidents. The results also suggest that temporal factors may exist, so additional research is warranted to better understand these factors and potentially develop interventions. This research provides a data-driven foundation from which future research can be conducted for safety interventions to reduce the frequency and severity of incidences involving the roof bolter activities of bolting, handling of materials, and setting the TRS.
锚杆支护通常在开采某种商品之后进行，以帮助防止顶板坍塌。在2004年至2013年期间，锚杆钻机操作员在地下煤矿中遭受的与机械相关的伤害数量最多，占64.7%。本文分析了2004年至2013年美国所有商品在地下作业场所的锚杆钻机致命和非致命误工伤害数据，并确定了六项锚杆支护任务的风险指数。对于致命和非致命事故综合来看，按风险指数从高到低排序的锚杆支护任务依次为锚杆安装、材料搬运、设置临时顶板支护（TRS）、钻孔、运输和行走。对于死亡事故，按风险指数从高到低排序的锚杆支护任务依次为材料搬运、设置TRS、锚杆安装、钻孔、行走和运输。年龄被发现是一个重要因素。以误工天数表示的伤害严重程度随着年龄的增长以及经验的增加而增加，这主要是由于年龄和经验的混杂。鉴于事故的高频率和严重性，地下采矿中使用的锚杆钻机的操作应成为研究重点。结果还表明可能存在时间因素，因此有必要进行更多研究以更好地理解这些因素并可能制定干预措施。本研究提供了一个数据驱动的基础，在此基础上可以开展未来研究以进行安全干预，从而减少涉及锚杆安装、材料搬运和设置TRS等锚杆钻机活动的事故频率和严重程度。
