【摘要】 近年来,三下采煤技术得到快速发展,宽条带在建筑物下广泛应用,水体下采煤开采上限一再提高,这主要得益于覆岩破坏探测技术的新进展。介绍了近期在三下采煤中应用成功的几项新的探测方法,包括利用EH-4电导率成像系统探测地层构造和覆岩破坏形态;用彩色钻孔电视系统观测覆岩中裂缝发育形态、宽度和渗水性能,确定两带高度;通过Sondex沉降仪和Sinco倾斜仪观测工业场地第四系地层沉降,预测井筒破坏时间并根据沉降量提出井筒治理方案。更多还原

【Abstract】 In recent years,coal mining under buildings,railways and water bodies obtain the fast development,the widespread application of the wide strip belt under the building,mining under water,upper mining limit enhances repeatedly,all these mainly benefits from the new progress of Detection method and survey technology.This article introduced the successful several new survey method with emphasis in coal mining under buildings,railways and water bodies in the near future applies,including will use EH-4 conductivity imaging system survey stratum structure and overlying rocks failure shape;With the colored drill hole television system observation overlying rocks failure shape in the crack developmental morphology,the width and the seep performance,determine two belt altitudes;Through the Sondex settlement and the Sinco inclinometer observation the stratum subsidence,forecast the mine shaft damage time and proposes the mine damage government plan according to the subsidence quantity.更多还原
