工程探测与分析采空区分布对安全开采具有现实必要性。以乌东煤矿43“煤层东翼采空区分布预测为目标，通过现场工程地质与开采条件调查、电磁波能量传播机制分析、现场地面地下协同地质雷达（Ground Penetrating Radar，GPR）快速与多次扫描与复测等，对比分析了走向剖面既定扫描区域（1050m×80m）沿不同走向长度、水平标高和垂向深度网点地质雷达扫描波形与时间剖面特征，定量预测了4-640-＋720水平80．0m范围煤岩破碎特征和走向50—800m垂深70．0m采空区分布位置，指导了现场采空区预处置设计、灾害防治与安全生产。

英文摘要：

It is essential for promotion safe mining and efficiency to both analyze and engineering detect the distribution of mined-out-area. There existing abundance abandoned mined-out-area adjacent to the mining disturbed zone （MDZ） are prone to the stability problems and dynamical hazard ensue, inevitably, it constraints safe mining at Urumchi steep coal seam region. Taking aim of prediction to mined-outarea distributing conditions upwards the eastern of No. 43 coal seam of Wudong Mine, applied the field engineering geology and mining conditions inquisition, electromagnetic waves transfering mechanism a- nalysis relating rockmass structure ,field tridimensional ground renetrating radar（GPR） （surface and underground）, rapid, multiple scanning and repetition measurement, etc. , a comparison of characteristics on both the GPR scanning wave profile and time section had been performed at defined scanning region of which lateral setion ranging covered 1050m 80m, by a network of various strike length and horizontal bedding planes and vertical depth. The broken characteristics and predictive location of mined-out-area distributions,with strike from 50 m to 800 m,vertical 70.0 m depth, had been quantitatively confirmed wherein a 80 m depth ranging from 640 to 720 level. All of results guided the field design for pre-disposal mined-out-area, hazard precaution and safe mining.
