物探预测预报技术在综采矿井中的应用探讨

以打通一煤矿综采工作面巷道中全覆盖探测为例,总结了茅口灰岩巷道掘进碛头前方岩溶、地质构造的波形特征和探测方法,并在煤系地层中进行顺煤层探测和穿煤层探测试验。分析了现阶段物探仪在茅口灰岩巷道、半煤巷道和穿层巷道探测中的成功经验和存在的问题及应用后产生的效益,指出该仪器在矿井有着广阔的应用前景,值得大力推广。

Probe into the Application of Geophysical Prospecting Prediction Technology in Fully-mechanized Coal Mine

Taking fully-covered detection used in breaking through the roadway of a coal mine’s fully-mechanized mining face as an example,this paper sums up the waveform characteristics of and detection methods for excavation top Karst and geological structure of Maokou limestone roadway,and makes the detection tests along the coal seam and across the coal seam in coal measure strata,and analyzes some successful experiences,existing problems and gained benefits of applying geophysical prospecting instrument in the detection of Maokou limestone roadway,semi-coal rock roadway and across seam roadway,and points out that this instrument has broad application prospect in coal mine Should be vigorously promoted.
