Abstract

Mining has historically been known as a high-risk industry. Coal and gas outbursts are one of the most significant accidents that occur in underground coal mines. Despite many years of research, the resources and mechanisms of this phenomenon are not well understood. Thus, it is difficult to forecast and control these events. As the mining depth and density increase, initial gas pressure and gas content of coal seams continue to increase, and the risk of explosion increases. Hence, explosion-prone areas expand gradually. As a result, a dynamic phenomenon has emerged in areas where there is no danger of outbursts. The risk of outbursts becomes more and more serious in coal mines. A coal outburst risk assessment includes evaluating the risk factors to what degree are present and then determining the risk areas of the mine. In this study, the Cluster Analysis method was implemented to identify the risk level of coal seams based on the evaluation of the outburst risk factors for an underground coal mine. Coal and gas outbursts occurring in Zonguldak hard coal basin were divided into two clusters, Cluster A and Cluster B. Coal seams in Cluster A were determined riskier than Cluster B coal seams.

基于聚类分析法的煤与瓦斯突出危险性评价

采矿业历来被认为是高风险行业。煤与瓦斯突出是煤矿井下发生的重大事故之一。尽管经过多年的研究，这种现象的来源和机制仍未得到很好的理解。因此，很难预测和控制这些事件。随着开采深度和密度的增加，煤层初始瓦斯压力和瓦斯含量不断增加，爆炸危险性增大。因此，易爆炸区域逐渐扩大。因此，在没有爆发危险的地区出现了一种动态现象。煤矿矿井突水危险性日益严重。煤突出危险性评价包括评价危险因素的存在程度，进而确定矿井的危险区。本文在对某地下煤矿突出危险因素进行评价的基础上，采用聚类分析方法对煤层危险性等级进行识别。将Zonguldak硬煤盆地的煤与瓦斯突出划分为A和B两类。A类煤层的危险性高于B类煤层。

期刊介绍： Acta Montanistica Slovaca publishes high quality articles on basic and applied research in the following fields: geology and geological survey; mining; Earth resources; underground engineering and geotechnics; mining mechanization, mining transport, deep hole drilling; ecotechnology and mineralurgy; process control, automation and applied informatics in raw materials extraction, utilization and processing; other similar fields. Acta Montanistica Slovaca is the only scientific journal of this kind in Central, Eastern and South Eastern Europe. The submitted manuscripts should contribute significantly to the international literature, even if the focus can be regional. Manuscripts should cite the extant and relevant international literature, should clearly state what the wider contribution is (e.g. a novel discovery, application of a new technique or methodology, application of an existing methodology to a new problem), and should discuss the importance of the work in the international context.
