摘　　要：针对煤矿瓦斯浓度监测和安全预警需求及井下环境特点,提出一种煤矿井下瓦斯浓度数据采集策略和数据融合及预警方法。介绍煤矿井下瓦斯浓度数据采集策略和相应监测系统的硬件构成,提出一种利用模糊综合评判模型对瓦斯浓度数据进行融合的方法,给出各瓦斯浓度数据监测区域和监测点的权重分配方案,结合实例描述多监测区域多监测点的瓦斯浓度数据融合与结果评判及预警方法。实验结果表明,该方法能够更为全面地获取井下多区域多地点瓦斯浓度数据,有效避免极端数据对判别当前通风环境下瓦斯浓度数据的影响,瓦斯浓度数据融合与评判结果更为客观准确。To deal with the need of gas density monitoring and safety pre-warning in the coal mine,an approach for collecting and fusing the gas density data in the coal mine as well as the safety pre-warning was proposed.The strategy for collecting gas density data and the hardware construction of monitor system were introduced.The method for fusing the gas density data was presented by leveraging the fuzzy synthetic evaluation model,an algorithm for choosing the weights assignment proposals was also proposed.The fusing and evaluating approach for gas data from multi-monitoring area and multi-monitoring point was described by incorporating a concrete example.The results of system implementation demonstrate that the approach proposed can capture more complete data from multi-areas and multi-points in the coal mine and it can also remove the influence of incorrect data on evaluating the gas density of current ventilation environment.As a result,the gas density data fusion and evaluation becomes more objective and accurate.
