新疆哈密大南湖矿区北露天煤矿首采区东南部需要揭露Ⅲ火烧岩区一部分，这使得烧变岩水成为露天煤矿矿井充水的主要水源。资源勘探阶段的水文地质资料表明，烧变岩区赋水空间发育、透水能力强，储存量非常可观，但由于受资源勘探阶段水文地质勘探工程量制约，水文地质条件未能详细查明。因此为达到查明烧变岩地下水水力联系、水质变化情况，充分暴露Ⅲ火烧区烧变岩的水文地质条件的目的，设计了该次群孔抽水试验。该次试验查明了烧变岩含水层的水文地质条件，为烧变岩地质条件下防治水工作提供了依据。综合分析表明Ⅲ火烧区烧变岩为储存量型含水层，其补给条件差。

Portions of the Ⅲ burnt rocks in south part of the first mining area of northern open pit coal mine in Dananhu mine of Hami in Xinjiang should be exposed.It makes the burnt rock water become the main source of mine water filling.As showed by hydrogeological data in exploration stage,water bearing space in burnt rock area developed well with permeable capability and large storage capacity.Due to the limit of hydrogeological exploration engineering amount in exploration stage,hydrogeological condition has not been identified in detail.In order to find out water contact and the groundwater water quality changes of burnt rock,and to fully expose the hydrogeological conditions of the burnt rocks in Ⅲ burning area, group drilling pumping test has been designed.This test has identified hydrogeological conditions of burnt rocks,provided the basis for water prevention work under the condition of burnt rock.Through compre-hensive analysis,it is showed the burnt rocks in Ⅲ burning area are aquifer storage capacity type with poor supply conditions.
