【摘要】：活鸡兔井在掘进2-2煤三盘区巷道期间,对相邻的越界开采的小窑采空区施工了钻孔进行探放水,由于水量大,且泄放钻孔周围也存在淋水,一旦井下抽排不及时就会形成积水,给矿井安全生产带来隐患。为了消除小窑泄水点给矿井带来的水害隐患,保证矿井安全生产,经过研究确定了小窑采空区水害的治理方案。其方案中确定了人工挡水坝体的实施位置、坝体的施工设计和施工工艺。人工挡水坝体施工完成后,挡水严密、可靠,取得了良好的水害治理效果,实现了变水害为水利。
[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.
