滕州郭庄煤矿十二采区第十下层灰岩水赋存规律及涌水量预测

Occurrence Rule and Water Sprouting Amount of Limestone Water in Lower Part of the Tenth Layer in the 12th Mining Area in Guozhuang Coal Mine of Tengzhou City

摘要:

采区涌水量是采区排水系统设计的依据，涌水量的准确与否，直接涉及到采区开采的安全。该文对十下层灰岩的涌水规律、补给条件进行了分析，并采用比拟法及大井法对采区涌水量进行了计算，预计了采区正常涌量和最大涌水量，为采区排水设计提供依据。

Abstract:

Water sprouting amount of mining area is the basis for designing drainage system. Precision of water yield will influce the safety of coal exploitation in mining area directly. Water sprouting rule and supply condition of the lower part of the 10th lime
