【摘要】：活雞兔井在掘進(jìn)2-2煤三盤區(qū)巷道期間,對相鄰的越界開采的小窯采空區(qū)施工了鉆孔進(jìn)行探放水,由于水量大,且泄放鉆孔周圍也存在淋水,一旦井下抽排不及時就會形成積水,給礦井安全生產(chǎn)帶來隱患。為了消除小窯泄水點(diǎn)給礦井帶來的水害隱患,保證礦井安全生產(chǎn),經(jīng)過研究確定了小窯采空區(qū)水害的治理方案。其方案中確定了人工擋水壩體的實施位置、壩體的施工設(shè)計和施工工藝。人工擋水壩體施工完成后,擋水嚴(yán)密、可靠,取得了良好的水害治理效果,實現(xiàn)了變水害為水利。
[Abstract]:During the excavation of the 2-2 coal three-disk roadway in Huojiyu well, the boreholes in the adjacent small kiln goaf areas that were exploited across the boundary were constructed to explore and discharge water. Because of the large amount of water and the existence of water around the discharge holes, water would form when the underground drainage was not timely. In order to eliminate the hidden dangers brought to the mine by the small kiln discharge point, and to ensure the safe production of the mine, Through the study, the project of water hazard control in mined-out area of small kiln is determined. In the scheme, the position of artificial water retaining dam body, the construction design and construction technology of the dam body are determined. After the construction of artificial water retaining dam body is completed, the water retaining dam body is strict and reliable. A good effect of water disaster control has been achieved, and the change of water hazard to water conservancy has been realized.
