Study On The Treatment Technology Of Water-inrush From Coal Seam Floor With Gig Mining Depth

With the mining depth increasing, geological, hydrological and geological conditions become more complex, mine safety threat will gradually increase. In recent years, mine water inrush occur frequently, how fast and high quality of water bursting channel to implement effective plugging is an urgent need to resolve important issues. According to the characteristic of the colliery and its vulnerability, must establish the corresponding technological route and management program, to achieve the desired control objectives.In this paper, through a large number of field investigation and related analysis, present condition of deep mining management water inrush and basic thought of governance in the process of key and difficult problems, and put forward the effective solution. In certain mine concealed miniature collapse column water bursting of the specific circumstances, to identify the source of water inrush based on, analyzed the possibility of water inrush channel and water inrush mechanism; using field experiment, indoor experiment and indoor analysis, identified in the hydrodynamic conditions of the key technical parameters of grouting and blocking water; use of vertical borehole Kong Xie correction technique and branch pore-forming technology, quickly determine the water inrush channel types and spatial characteristics; the" blocking source cap" technical proposal, take intermittent Grouting grouting grouting holes at the same time, a single hole joint grouting technology and process, to achieve water bursting point and water conducted fissure effective plugging.
