【摘要】 针对煤矿瓦斯爆炸灾害问题,应用统计分析方法建立了以瓦斯浓度与着火温度为主要因素的瓦斯爆炸诱因预警模型,将瓦斯爆炸诱因预警划分为4个等级.在GIS技术支持下,开发了基于ArcViewGIS的预警模块,结合瓦斯传感器及温度传感器建立了预警系统.以平顶山煤业集团天安十二矿典型工作面为例,验证了预警技术的可行性.更多还原

【Abstract】 Aiming at the gas explosion problem of safety production process in coal mine,the statistics method was adopted for founding math models of gas thickness and fire temperature.Compartmentalizing four grades of gas explosion inducement,by GIS,the forewarning program was empoldered.Combining gas sensor and temperature sensor,the forewarning system established is applied in Tianan No.12 Coal Mine of Pingdingshan Coal Mining Group Corp.Ltd.and the forewarning technique is feasible.更多还原
