Kömür Damarlarının Gaz Ġçeriğinin Belirlenmesi; Örnek Bir Uygulama

Artan üretim miktarları ile üretim panolarının daha derinlere ulaĢması, çalıĢılan ayağın önündeki kömür damarlarının gaz içeriğinin belirlenmesine yönelik talebi de beraberinde getirmiĢtir. Aynı zamanda kömür damarlarının gaz içeriğini etkileyen parametrelerin birbirleriyle olan iliĢkilerinin biliniyor olması, doğru bir tahmin için son derece önemlidir. Elde edilen verilerin değerlendirilmesi, özellikle iĢçi sağlığı ve iĢ güvenliği açısından ve verimli bir iĢyeri planı ortaya koyulması yönünden ayrı bir hassasiyete sahiptir. Bu çalıĢmada, kömürlerin gaz içeriğinin tespitine yönelik yapılan çalıĢmalar ile birlikte, Gedizde (Kütahya) bir kömür ocağından elde edilen numunelerin gaz potansiyeli araĢtırılmıĢ yapılan deneysel çalıĢmalar detayları ile birlikte verilmiĢtir.

The Determination of Gas Content of Coal; A Case Study

Increased production rates and deeper panel locations have brought about the demand for the determination of the gas content of coal beds ahead of the working face. It is also important to know the association of the parameters with each other for an accurate estimation of gas content of the coal seams. Evaluation of the data obtained has a distinct precision specifically for the occupational health and safety as well as realizing an efficient workplace. In the present work, the practices towards the determination of gas content of the coal are outlined together with the explanation of an experimental work carried out on the coal samples taken from a colliery in the province of Gediz (Kütahya).
