为准确评价南峪煤矿下组煤层底板奥灰突水危险程度,以8~#煤层开采为例,分析确定煤层底板突水的主控因素,运用基于GIS和AHP耦合理论的脆弱性评价模型,对8#煤层底板突水危险性作出评价并分区。将脆弱性指数法与传统突水系数法评价结果进行对比分析,结果表明,脆弱性指数法较全面地反映不同区域的相对脆弱关系,其评价结果更为真实可靠。
In order to accurately evaluate the dangerous degree of the inhomogeneous water inrush from the coal seams in Nanyu coal mine, taking the mining of No.8 coal seam as an example, the main controlling factors for water inrush from coal seam floor are analyzed and analyzed. The vulnerability assessment model based on GIS and AHP coupling theory is adopted. 8 # seam floor water inrush risk assessment and zoning. Comparing the results of Vulnerability Index and traditional water inrush coefficient method, the results show that the Vulnerability Index method reflects the relative fragility of different regions comprehensively, and the evaluation results are more reliable.
