摘要
为确保采面回采安全、掌握61303综采工作面内隐伏地质构造位置及分布情况,采用无线电波透视技术对采面内隐伏构造进行探测,并依据采面实际情况对探测方案、探测流程等进行设计。现场探测发现采面内存在煤层变薄区以及落差在1.5 m以内的断层,回采巷道掘进以及钻探也验证了物探成果。通过在61303综采工作面内进行无线电探测,可提高回采工作面安全生产保障能力。
In order to ensure the mining safety of the mining face and master the location and distribution of hidden geological structures in61303 fully mechanized mining face, the radio wave perspective technology is used to detect the hidden structures in the mining face, and the detection scheme and detection process are designed according to the actual situation of the mining face. The on-site detection found that there were coal seam thinning areas and faults with a drop of less than 1.5 m in the mining face. The excavation and drilling of mining roadway also verified the geophysical exploration results. Through radio detection in 61303 fully mechanized mining face, the safety production guarantee capacity of mining face can be improved.
