-
摘要: 通过先进的勘探设备与技术实现综采工作面的透明化,使煤层信息更加全面、准确,可为综采工作面的智能化生产奠定坚实的基础。直流电阻率法是矿井物探常用方法,其稳定性好、抗干扰能力强,对低阻体和高阻体都有灵敏的反映能力,因此直流电阻率法是实现工作面透明化的关键手段之一。为探究直流电阻率法在工作面透明化中的应用效果,对工作面探明含水构造、巷道迎头超前探测等问题,分别使用不同的工作方法对两种问题的响应特征进行三维正、反演。结果表明在对应的工作方法下得到的三维直流反演数据分布规律与初始模型基本一致,有良好的高、低阻体区分能力。对实际工程中直流电阻率法在工作面透明化中的应用有一定指导作用。Abstract: The transparency of the fully mechanized mining face achieved using advanced exploration equipment and technology can make the information on coal seams more comprehensive and accurate and can lay a solid foundation for the intelligent production of the fully mechanized mining face. DC resistivity method is a common method for geophysical exploration. Owing to the high stability, great anti-interference performance, and sensitive responses to low- and high-resistance bodies, the DC resistivity method is one of the key means of achieving the transparency of the mining face. To explore the application effects of the method in the transparency of the mining face, this study used different working methods to conduct three-dimensional forward and inverse modeling of the response characteristics for solving proven water-bearing structures of the mining face and frontal advanced detection of roadways. The results show that the distribution laws of 3D DC inversion data obtained by corresponding working methods were basically consistent with those of the initial model, and the DC resistivity method can well distinguish between high- and low-resistivity bodies. Therefore, this study can guide the application of the DC resistivity method in the transparency of mining face in practical engineering.
