摘要
车集煤矿2604工作面受邻近工作面老空积水影响严重,传统探放水工程量大,安全系数低,已无法满足矿井高效生产的需求。针对此情况,2604工作面下巷掘进期间采取无煤柱沿空掘进的方式,改“探放水”为“疏排水”,通过“可视化”疏放老空水,取代探放老空水钻探施工,多回收了2.91万t煤柱,在提高安全系数和生产效率的同时,增加了2328万元的经济效益,技术应用效果极为突出。
The 2604 working face of Cheji Coal Mine is seriously affected by the water accumulation in the adjacent working face.The traditional water exploration and drainage works are large and the safety factor is low,which can not meet the needs of efficient production of the mine.In view of this situation,the 2604 working face adopts the way of driving along the goaf without coal pillar during the driving period,changing"water exploration and drainage"to"drainage",through the"visualization"drainage of old goaf water,replacing the drilling construction of old goaf water exploration and drainage,more than 29100 tons of coal pillars are recovered,which improves the safety factor and production efficiency,increases the economic benefit of 23.28 million yuan,and the technical application effect is extremely outstanding.
