摘要
本文介绍了永晟煤矿巷道工作面的水文地质条件、综合监测系统构成及安装布置条件,阐述了综合监测系统的运行环境和无线监测技术在煤矿井下开采中的适用性;根据综合监测系统监测得到的数据参数,得出了微震、应力和瓦斯涌出量在煤与瓦斯突出过程中的相互响应关系;根据工作面的实际情况,采用上隅角插管抽采和顺层双向平行钻孔预抽瓦斯作为工作面的防突措施。
Hydrogeological condition,integrated monitoring system and installation of the roadway working face were introduced,the operation environment and wireless monitoring technology of underground integrated monitoring system were discussed,relationship of microseismic,stress and gas emission in coal and gas outburst based on data parameter of comprehensive monitoring system,outburst prevention measures of upper corner piping drainage and two way parallel drilling were adopted.
