安徽五沟煤矿1016面底板突水GMS模拟模型研究

Study on GMS Simulation Model of Floor Water Inrush in No.1016 Coalface of Anhui Wugou Mine

由于水文地质条件的复杂性和开采技术的多样性,目前底板水的运移及突水量预测仍然较为困难。根据五沟煤矿现场工程地质、水文地质条件,通过概化水文地质条件,建立数学模型。采用GMS软件,建立1016面开采涌水模拟模型,通过对模型的检验分析,验证模型的准确性,为深入系统地研究五沟煤矿1016工作面底板岩层破坏机理和突水条件以及为煤矿防治水设计提供依据。

Because of the complexity of the hydrogeology and variety of mining technology, it is still difficult to master the floor water movement and predict the quantity of water inrush. This paper, based on the field conditions of engineering geology and hydrogeology in Wugou Mine, set up a mathematical model by predigesting the hydrogeo- logical condition, and established a simulation model of water inrush in the mining of No. 1016 Coalface by using GMS. Then, according to the checking analysis of the model, the veracity of the model was validated, providing a basis for the deep and systematical research on the rules and conditions of the floor water inrush in No. 1016 Coalface of Wugou Mine and also for the design of water prevention in coalmines.
