河南栾川钼矿多层采空区充填井成井工艺

Filling Well Completion in Multilayer Goaf of Luanchuan Molybdenum Mine

由于地下开采形成了大量的采空区,容易发生坍塌事故,尤其对于从地下开采转为露天开采的矿山影响很大,对矿区的安全生产造成隐患,因此对采空区的处理十分重要。针对这一现状,本文研究了一种多层采空区充填井成井工艺,以对多层采空区进行支护处理。通过这种工艺可以减少岩石的移动幅度,防止大面积的地压活动,为矿区的生产和安全提供保障。由于各个矿山的条件不同,采空区的具体位置、形态特征及大小等的不同,对采空区处理方法也不尽相同,本文针对河南省栾川钼矿采空区的特点进行充填井成井工艺的研究与试验。

Because of the underground mining,a large number of goaf are formed,the collapse accident is prone to happen,especially for the mines from underground mining changing into open-pit mining,there are hidden dangers to the safety production of the mining area.In view of this situation,this paper studies a filling well completion technology for multi-layer goaf to carry out support treatment.By means of this process,the amplitude of rock movement can be reduced to prevent the large area of ground pressure activities,so as to provide guarantee for the production and safety.Due to the different conditions of the specific location,morphological characteristics and size of the goaf in each mine,the treatment methods for goafs are not the same.According to the characteristics of Luanchuan molybdenum mine goaf,this paper introduces the study and test on filling well completion technology.
