摘要
随着煤矿安全高效开采需求的不断提高,特别是综采工作面对基于高精度地质模型的自主截割技术的研究和应用,对综采工作面三维地质建模的精度和时效性提出了更高的要求。为提升神东矿区综采工作面地质模型的快速构建、高效存储及动态更新能力,建立了基于GIS的综采工作面高精度地质建模系统,统一融合、协同处理综采工作面地质模型数据。由于综采工作面建设初期有效的地质成果资料少,为了保证地质模型的精度,通过采集综采工作面相邻已采工作面或外扩多边形内的煤层和构造控制点数据,在统一坐标系下融合资源勘探数据、三维地震数据等多源异构数据,集成处理生成满足地质规律的综采工作面基础地质模型,再经过平剖面对应等对地质模型加密处理,进一步提高分辨率,实现模型精细化。同时,随着综采工作面的不断推进,针对以写实数据为基础的新生产数据的加入,利用二三维一体化、膨胀搜索、样条曲面、边界平滑等业务逻辑和算法修正基础地质模型,生成更逼近真实的能反映工作面当前生产状况的综采工作面高精度地质模型。基于建立的综采工作面高精度地质模型提出了自适应工作面截割路径规划的方法,提高了综采工作面地质模型动态更新的效率和实用性,能够为综采工作面智能化开采提供煤层的三维基础地质数据,为神东矿区透明地质保障系统和工作面智能综采自适应截割路径规划提供了技术支持和保障。
With the continuous increase in the demand for safe and efficient mining in coal mines,especially the research and application of autonomous cutting technology based on high-precision geological models in fully mechanized mining faces,higher requirements have been put forward for the accuracy and timeliness of 3D geological modeling of fully mechanized mining faces.In order to enhance the rapid construction,efficient storage and dynamic updating capabilities of the geological model of fully mechanized mining face in Shendong mining area,a high-precision geological modeling system for the fully mechanized mining face was established based on GIS,which integrated and collaboratively processed geological model data of the fully mechanized mining face.Due to the limited availability of effective geological data during the initial construction of the fully mechanized mining face,in order to ensure the accuracy of the geological model,coal seam and structural control point data from adjacent mined working faces or expanded polygons of the fully mechanized mining face were collected.Resource exploration data,3D seismic data and other heterogeneous data were integrated and processed in a unified coordinate system to generate a basic geological model of the fully mechanized mining face that met geological rules.Then,the geological model was encrypted through plane and section correspondence to further improve resolution and achieve model refinement.At the same time,with the continuous advancement of the fully mechanized mining face,in response to the addition of new production data based on realistic data,the basic geological model was modified by using business logic and algorithms such as 2D-3D integration,expansion search,spline surface and boundary smoothing to generate a high-precision geological model of the fully mechanized mining face that was closer to reality and could reflect the current production status of the mining face.Based on the established high-precision geological model of the fully mechanized mining face,a method for guiding the cutting path planning of the mining face had been proposed,which improved the efficiency and practicality of dynamic updating of the geological model of the fully mechanized mining face,and could provide 3D basic geological data of coal seams for intelligent mining of the fully mechanized mining face,and provide technical support and guarantee for the transparent geological guarantee system and intelligent fully mechanized mining adaptive cutting path planning in Shendong mining area.
