Tectonic Coal Distribution Features and Cause Analysis of 11₂ Coal Seam in Xinji No.1 Mine

In order to master the distribution features and reasons of the tectonic coal in 11₂ coal seam of Xinji No.1 Mine. We apply the borehole logging curves to identify and count the tectonic coal thickness of each borehole in No. 11₂ seam and to draw the thickness isoline of the structure seam. Based on the circumstances, we analyze the distribution features of 11₂ coal seam tectonic coal. The results show that the structure coal within the mine field was generally developed, especially the tectonic coal thickness increased in the fault zone development core area of F₁₀ fault and the synclines core position. Tectonic coal development influenced by Fufeng Nappe Structural Belt early formation and the late fault and fold transformation.
