岩石膨胀界限抗渗强度及在底板突水评价中应用
Rock Expansion Boundary Anti-Permeability Strength and Its Application in the Coal Mine Floor Water Inrush Evaluation
摘要
Abstract
To solve the difficulties in coal mine floor water inrush evaluation, on the basis of the servo-controlled permeability test of rock in the complete stress-strain process, we proposed the concept of rock expansion boundary anti-permeability strength, and established a theoretical evaluation model of floor water inrush. In the model, several factors, such as the floor aquifuge effective thickness, lithology, rock mass integrity, and expansion boundary anti-permeability strength were considered, and the taking values of all factors were described in detail. Taking the No. 17 coal seam and 2702 working face in Yangcun coal mine, Yanzhou mining group as an example, it proves that the evaluation model based on the expansive boundary anti-permeability strength is feasible to evaluate the coal mine floor water inrush.关键词
