摘要
为了解决山西某煤矿15102综放工作面粉尘浓度高,煤层氧化剧烈、瓦斯突出现象严重等问题,针对该工作面的地质特征和开采技术等特点,设计了长孔静压注水措施技术。通过现场测试注水效果数据表明:煤层注水能有效降低采煤工作面和巷道的粉尘量,降低工作面温度,防治煤层进一步氧化。证实长孔静压注水技术适用于高瓦斯突出矿井厚煤层开采工作。
In order to solve the 15102 caving coal face exchange high concentration of dust,coal oxidation violent outburst serious problems for the face and other geological features and characteristics of mining technology,the design of the long hole injection technology.Test the water through the field effect data show that:Seam water can effectively reduce the efficiency of the coal face and roadway dust,reducing face temperature,preventing further oxidation of coal.Confirmed long hole hydrostatic water injection technology for high gas outburst thick seam mining work.
