摘　　要：为准确、合理地评价和划分煤矿开采区块等级,指导矿井精准、安全、高效生产,以新集矿区11^(-2)煤层为研究对象,选取煤厚、地质构造、水害、瓦斯灾害作为主要评价指标,基于Arcgis平台分别建立了构造复杂程度模糊评判分区模型、顶板突水脆弱性指数分区模型、瓦斯突出熵变权TOPSIS分区模型。以分区模型为基础,结合矿区实际开采地质条件,采用GIS图形加权叠加方法,将矿区划分为不利、威胁、可改造、较有利与有利5个等级的开采区块。同时,将本次评价分区结果与实际灾害点对比分析发现,已发生的灾害点均位于不利开采区块与可改造区块内,验证了本次评价模型的合理性与可行性,其评价结果可为矿区煤炭开采统一规划布局与防灾减灾工作提供科学指导。To accurately and rationally assess and grade coalmine extraction blocks,guide mine exact,safe and efficient production have taken coal No.11^(-2) in the Xinji mine area as subject investigated.Coal thickness,geological structure,water hazard and gas disaster etc have been selected as main assessment indices,based on ArcGIS platform established structure complexity fuzzy judgment zoning model,roof water bursting vulnerability index zoning model and gas burst entropy change weight TOPSIS zoning model respectively.Based on above zoning models,combined with mine area practical mining geological conditions,using GIS image weighted superposition has zoned mine area into unfavorable,threatened,transformable,rather favorable and favorable 5 graded extraction blocks.Meanwhile,compared this assessment grading results and actual disaster points comparative analysis has shown that happened disaster points are all situated in unfavorable and transformable blocks,thus verified rationality and feasibility of the assessment models.The assessed results can provide scientific guidance for mine area exploitation unified planning,layout,and disaster prevention,mitigation works.
