摘要
贺西煤矿3303工作面回采过程中,瓦斯尾巷底鼓严重,影响下一工作面正常使用,致使采掘接续紧张。本文以贺西煤矿3303工作面为背景,深入分析巷道底鼓影响因素,剖析瓦斯尾巷底鼓机理,并对瓦斯尾巷底鼓量构成进行分析。根据对瓦斯尾巷底鼓影响因素、底鼓机理及底鼓量构成分析,为后续瓦斯尾巷底鼓治理提供理论依据。
The floor heave phenomenon of gas tail gateway at 3303 working face are so severe during mining procedure that it has seriously effected the normal use of next working face and made the digging link strained in Hexi Coal Mine. The paper analyses the factor of big amount of floor heave of gas tail gateway, the mechanism and amount of floor heave based on the actual project of gas tail gateway of 3303 working face. The analyses based on impact factors mechanism and amount of floor heave, the theoretical basis was provided for control of floor heave.
