【摘要】 在极其复杂地表条件下,对淮北矿区某采区进行了三维地震勘探工程,针对区内大型河流、村庄及其他障碍物给三维地震勘探工程中测量、激发、接收、观测系统设计方案实施等造成的不利影响,采用了多种三维地震勘探技术手段。测量采用实时差分(RTK)的方法放样,利用K lseis软件针对复杂地形进行野外采集方案设计,在村庄中采用聚能弹激发,过河采用防水检波器接收及组合成孔激发以改善资料采集效果,在施工中针对实际情况采取相应技术措施。结果在极其复杂的地表条件下取得了良好的地震地质结果,共解释断层172条,为煤矿采区开拓巷道布设提供了可靠的地质资料。更多还原

【Abstract】 In order to complete a 3D seismic exploration project in a mining block of Huaibei Mining Area under an extreme complicated surface conditions,according to the large river,villages and other obstacles in the project area caused unfavorable influences to the survey,excitation,receiving,observation system design plan implemented for the 3D seismic exploration,multi 3D seismic exploration technical means were adopted.The on time difference(RTK) method was applied for the laying off of the survey.The Klseis software was applied to the design of the site data collection according to the complicated topography.In the villages,the energy accumulated balls were applied for the excitation.The water proof detector was applied for the data receiving when the operation crossed the river and the combined boreholes were applied for the excitation in order to improve the information collected results.The relative technical measures had been made according to the actual conditions during the construction period.As a result,good seismic geological achievements had been obtained under the ultra complicated surface conditions.The geological mission was completely made with 172 faults explained,which could provide the reliable geological information for the development gateway layout in the mining blocks of the mine.更多还原
