摘要
煤层隐伏小断层的精细探测和准确预测,对预防煤矿地质灾害性事故至关重要。基于煤矿现行施工的穿层瓦斯抽采钻孔资料,利用Matlab数值计算和图形处理功能,通过编程计算煤层(顶)底板控制点三维坐标,绘制高精度煤层等高线图、等厚线图和三维立体图,进而实现定量预测煤层隐伏小断层位置、产状和性质。煤矿实例模型计算验证了利用瓦斯抽采钻孔资料预测煤层隐伏小断层的有效性和可行性。
Small fault is an important factor resulting in geological disaster of coal mine accidents, fine detection and accurate prediction are important for concealed small fault. Based on the current construction of a large number of across-layers gas drainage boreholes, using Matlab numerical calculation and graphic processing function, through the calculation of 3-coordinate of control points in coal roof/ floor by programming, drawing high precision contour, coal isopach map and three-dimensional graph, the location, occurrence and nature of small concealed faults in seam were quantitatively predicted. The calculation of mine model verified the efficiency and feasibility to predict small concealed faults by using gas drainage borehole.
