为了实现对采掘工作面进入突出危险区的监测和预警,以“十二五”国家科技支撑计划项目为支撑,进行了煤与瓦斯突出预警技术和预警准则建设的研究,着重探讨了李村矿日常预测以及瓦斯涌出方面预警指标的选择和临界值的确定,并在李村矿瓦斯灾害较为严重的掘进工作面得到应用。应用结果表明:预警平台可以根据相应的预警指标在工作面接近突出危险区域以及瓦斯涌出异常进行监测和预警,并且预警结果得到了验证,可以有效提高前方煤与瓦斯突出危险信息的监测,减少煤与瓦斯突出事故的发生。
In order to realize the monitoring and early warning of the coal mining face entering the prominent danger zone and the “Twelfth Five-Year Plan” national science and technology support project, the research on the pre-warning technology of coal and gas outburst and the precautionary criteria are carried out, The daily forecast of the village mine and the selection of the early-warning index and the critical value of the gas emission, and is applied in the more serious digging face of the gas disaster in Licun Mine. The application results show that the early warning platform can monitor and early warning according to the corresponding early warning indicators near the critical danger zone and the gas emission anomaly in the working face and the early warning result has been verified, which can effectively improve the monitoring of coal and gas outburst hazard information ahead and reduce Occurrence of Coal and Gas Outburst Accidents.
