松散含水层长距离大采面工作面开采对策研究

受开采沉陷影响,矿井回采工作面上覆地表河流往往对回采工作造成很大的安全隐患。为探明松散含水层对工作面回采可能造成的危害,制定各种勘查手段,施工地面水位观测孔,通过观测水位变化,论证地表含水层对回采工作面的影响,从而消除安全隐患,为矿井安全提供保障。

Research on Mining Countermeasures for Ultra-wide and Long-distance Working Face

Affected by mining subsidence,the overlying rivers on the mining surface of the mine often cause great safety hazards to the mining work.To ascertain the possible hazards caused by the loose aquifer to the mining face,various survey methods are formulated,the ground water level observation hole is constructed,and the influence of the surface aquifer on the mining face is demonstrated by observing the changes in the water level,which eliminates hidden safety hazards and provides guarantee for mine safety.
