【摘要】:為查明平頂山煤田二礦和吳寨礦寒武系灰?guī)r地下水集中徑流帶賦存情況,在探明礦區(qū)地質(zhì)斷層發(fā)育特征的基礎(chǔ)上,采用井下連通試驗(yàn)研究了地下水集中徑流帶的展布及成因和控水作用。研究結(jié)果表明:二礦和吳寨礦寒武系灰?guī)r地下水流速達(dá)3 320.05 m/d,含水層滲透系數(shù)達(dá)36 911.11 m/d,證明了地下水集中徑流帶的存在;二礦逆斷層及兩側(cè)斷層破碎裂隙帶的存在,是影響寒武系灰?guī)r含水層集中徑流帶空間展布的關(guān)鍵因素;集中徑流帶總體上控制著寒武系灰?guī)r地下水由西南向東北流動(dòng)、自淺向深的運(yùn)移。寒武系灰?guī)r地下水集中徑流帶展布特征的確定,為類似條件煤層底板水害的防治奠定了基礎(chǔ)。
[Abstract]:In order to find out the occurrence of groundwater concentration runoff zone of Cambrian limestone in Pingdingshan Coalfield No.2 Mine and Wuzhai Mine, the geological fault development characteristics of mining area are proved. In this paper, the distribution, genesis and water control effect of groundwater concentrated runoff zone are studied by means of underground connection test. The results show that the velocity of groundwater in Cambrian limestone reaches 3 320.05 m / d, and the permeability coefficient of aquifer reaches 36 911.11 m / d, which proves the existence of concentrated runoff zone of groundwater, the existence of fracture zone of reverse fault and fault on both sides of No. 2 mine. It is a key factor to influence the spatial distribution of the concentrated runoff zone of the Cambrian limestone aquifer, which generally controls the movement of the Cambrian limestone groundwater from southwest to northeast and from shallow to deep. The determination of the distribution characteristics of groundwater concentrated runoff zone in Cambrian limestone has laid a foundation for the prevention and control of water damage in coal seam floor under similar conditions.
