煤矿采区建筑物压煤问题日益严重,探明建筑物下煤层构造情况需要在在不同地域、不同地质条件选用合理的技术手段。本文以lj煤矿六采区为例,在实测地形基础上合理设计观测系统,选择有效技术参数,调整孔深和炸药量,村庄内加深炮孔深度使用小炸药量,测点数据准确完整;加强野外资料施工采集,科学严谨的内业处理解释,完成建筑物下三维地震勘探工程任务,取得了较好的地质成果。
Coal mining area building coal pressing problem is more serious, to determine the structure of coal seam under the building needs in different regions, different geological conditions, the selection of reasonable technical means. Taking the six mining areas of lj coal mine as an example, the observation system is designed rationally based on the measured terrain. The effective technical parameters are selected to adjust the hole depth and the amount of explosives. The depth of the blast hole in the village is reduced by using small explosives and the data of the measuring points are accurate and complete. Field data collection construction, scientific and rigorous domestic industry to explain, to complete the task of building three-dimensional seismic exploration project, and achieved good geological results.
