Abstract:

This work aims to classify the gas content zones for coking coal deposits using a Number-Size (N-S) fractal modeling considering the explosive and free gas data. The case study is the C۱ coking coal seam in the Parvadeh-۴ coal deposit in the central Iran. Following this, the N-S log-log plots are created, which indicate three populations regarding both the explosive and gas data exist. Proper zones for both data in the C۱ coking coal seam have explosive and free gas contents lower than ۹.۵ m۳/ton and ۱.۳ m۳/ton, respectively. The low-value gas content zone is located in the western part of the studied area, which is in the lowest depth of this coal seam. In addition, a high-value content zone exists in the E, NE, and SW parts of this area with explosive and free gas contents higher than ۱۳.۸ m۳/ton and ۲.۲ m۳/ton, respectively. These parts of the C۱ seam are dangerous due to a high volume of gas content. Moreover, the explosive and free gas contents have a positive correlation with high risk gas volume based on the famous standards.
