Review and prospect on design and construction technology of mine water bulkhead

Based on the reviev on the techical status of the mine water bulihead widely applied to the donestic and overseas coal mines.the paper inroduced the present conventional sructure type and appication conditon of the mine water bulkhead ,the regulaion and standardization ofthe water bulkhead design and construction. with the coal mining depth increased,he design and construction ofthe waer bulihead faed with the high water pressure,broken surounding rock.adverse con;truction environment and othe dificulties.The key technical problems existed in the design and construetion of the water bulkhead were proicded, inclding the lcatoselection.type selecion.calculation.satety coeficient seleced and standardized constouction and oters.The paper proved the rapid constuction of the water bulkheadacidic water long term sealed with the wafer bulkinead.,hysics and numericals inulation of the waterbulihead comprehensive utilization of the sealed wates the regulat:on and law of the water bulkhead constution and oter waterbulkhnead engineering and technical development tendency. The study showed that the design and construction technology of the water bulkhead woul till equire a continucus inovation and handig from a view of the mutl ciences and the design and construcionof te deep depth high pressure water bulkhead should give high attentions to the mechanics strength and impermeability performances,
