煤层浅孔注水在高瓦斯综采工作面的试验研究
|
摘要
本论文主要研究煤层注水的机理以及影响注水效果的各种因素和相关参数,结合新集一矿131103工作面实施煤层浅孔注水试验研究,利用FLUENT数值模拟软件模拟煤层湿润渗透规律,并采用化验煤样全水份含量的变化两种方法研究在不同注水压力和注水时间下的煤层湿润半径,再根据湿润半径的大小进行浅孔煤层注水的设计,调整注水参数,优化注水工艺,达到最佳煤层注水湿润效果的目的。
研究了综采工作面粉尘的主要来源及其分布规律,并依据实测数据分析比较了注水前后各主要产尘工序粉尘浓度的变化,得出煤层注水能够有效控制工作面的煤尘,起到非常理想的降尘效果的结论;研究了煤层注水可以增大检修班瓦斯的释放,减小生产班的瓦斯浓度,有效遏止了生产班瓦斯时常超限的现象;依据大量现场实测数据,分析了注水前后工作面瓦斯突出指标的变化,得出煤层注水在一定程度上可以预防煤与瓦斯突出事故发生的结论。
This paper main research on the mechanism as well as each kind of factor and the correlation parameter to influence irrigation effect of coal bed pours water, unify 131103 work faces of the 1st mine in Xinji coal bed shallow hole flood-pot-test research, uses the two method research of FLU-ENT value simulation software to simulate coal bed moist seepage rule, and uses the examinating the entire moisture content change of coal sample under the different inigation pressure and the irrigation time coal bed moist radius, according to the moist radius the size to carry on the design which the shallow hole coal bed pours water, adjustm irrigation parameter, and optimize irrigation craft, achieved the best moist effect goal of the coal bed pours water.
Studied the main dust origin and the distribution rule in working faces, and compared around the irrigation based on the measured data analysis the change of each mainly to produce the dust working procedure dust density obtained the coal bed to pour water can the active control working faces coal dust, got up the extremely ideal falling dust effect conclusion; Studied the coal bed to pour water may increase the overhaul class gas the release, reduced the production class the gas density, has effectively suppressed the phenomenon which the production class gas often surpassed limits; Rests on the massive scene measured data, has analyzed around the irrigation the working surface gas prominent target change, obtains the coal bed to pour water may prevent conclusion to a certain extent which the coal and the gas prominent accident occurs.
