薄煤层工作面瓦斯治理关键技术分析

Analysis on Key Technologies of Gas Control in Thin Coal Seam Face

薄煤层在开采的过程中非常容易受到存赋条件、开采工艺和设备因素等诸多影响。甚至在使用的过程中出现采空区冒落不充分、工作面风阻力较大和漏风严重等诸多的问题。最终就会使得薄煤层内部的瓦斯管理的工作变得非常困难。本文结合实际的案例,通过有效地优化钻孔施工工艺来调整瓦斯抽采的参数,从而才能够解决薄煤层工作面瓦斯治理过程中的难题。

In the process of mining,thin coal seam is very easy to be affected by many factors such as storage conditions,mining technology and equipment.Even in the process of use,there are many problems such as insufficient caving in goaf,large wind resistance in working face and serious air leakage.Finally,it will make the gas management in thin coal seam very difficult.In this paper,combined with actual cases,it adjusts the parameters of gas extraction through optimizing the drilling construction technology effectively,thus solving the problems in the process of gas control in thin coal seam working face.
