Madencilik, ölümlü iş kazalarının en fazla olduğu sektörlerden biridir. İstatistiklere göre, bu ölümcül kazaların çoğu metan patlamalarından kaynaklanmaktadır. Patlamanın olabilmesi için metanın belirli bir konsantrasyon oluşturması, yeterli oksijen ve tutuşturucu elementlere ihtiyaç vardır. Metan oluşumunu etkileyebilecek en önemli faktörlerden biri kömürün karbon içeriğidir. Karbon içeriği arttıkça, yanıcı hidrokarbon türevi gaz oluşma olasılığı artar. Gözenekli yapı, metanın birikmesine ve anlık konsantrasyon oluşturmasına neden olan bir faktördür. Ateşleme elemanının oluşumunun yan kayaçların kuvars içeriği ile doğru orantılı olduğu bilinmektedir. Bu çalışmada, tüm bu yan parametrelerin dilsel ifadelerine puan verilerek yeni bir risk değerlendirme yöntemi önerilmiştir. Önerilen bu yöntem, kesin ölçümler ve cebri havalandırma ilkelerinden bağımsız olarak proaktif bir yaklaşım sağlar. Bu doğrultuda alınacak tedbirlerle beklenmeyen sonuçların önüne geçilebileceği öngörülmektedir.

A Scoring-Based Risk Assessment Method Proposal for Methane Explosions in Underground Coal Mines

Öz

Mining is one of the sectors with the highest number of fatal occupational accidents. According to statistics, the majority of these fatal accidents are caused by methane explosions. In order for the explosion to occur, methane needs to form a certain concentration, sufficient oxygen and igniting elements are required. One of the most important factors that can affect methane formation is the carbon content of coal. As the carbon content increases, the probability of formation of flammable hydrocarbon-derived gas increases. The porous structure is a factor that causes methane to accumulate and create instantaneous concentration. It is known that the formation of the ignition element is directly proportional to the quartz content of the wall rocks. In this study, a new risk assessment method is proposed by assigning scores to the linguistic expressions of all these side parameters. This proposed method enables a proactive approach regardless of exact measurements and forced ventilation principles. It is foreseen that unexpected results can be prevented with the measures to be taken in this direction.
