TY - JOUR TI - Temperature field distribution of coal seam in heat injection AU - Zhang Zhizhen AU - Peng Weihong AU - Shang Xiaoji AU - Wang Kun AU - Li Heng AU - Ma Wenming JN - Thermal Science PY - 2017 VL - 21 IS - 11 SP - 39 EP - 45 PT - Article AB - In this article, we present a natural boundary element method (NBEM) to solve the steady heat flow problem with heat sources in a coal seam. The boundary integral equation is derived to obtain the temperature filed distribution of the coal seam under the different injecting conditions.
