采动矿区风电场工程的建设与保护技术

Construction and Protection Technology of Wind Farms Engineering in Mining Influencing Area

在压覆矿区兴建的风电场受井下采动影响存在着较大的安全隐患。通过分析风电场内主要建(构)建物——风机的采动变形特点,针对性地提出了风机"避、抗、测、修"一体的安全保护技术体系:结合地面与地下的条件,提出了对风机优化选址的原则;根据风机的结构特点,提出了风机抗变形结构技术措施;以风机倾斜为主要观测目标,进行了风机采动变形观测设计;针对风机受采动影响可能倾斜过大的安全风险,提出了适合于风机的基础纠偏维修措施。研究成果可实现采动影响区上方兴建风电场无保护煤柱条件下的长久安全运行,为压覆矿区兴建风电场开创了一条有效技术途径,具有较高的应用价值。

The wind farms built in the pressure-covered mine exist great security risks,which are affected by the underground mining. The security protection technology system of fans with the integration of avoidance,resistance,monitoring and repairing,is proposed typically,according to the analysis of mining and deformation characteristics of the fan which is the main structure in wind farms. Combining the conditions of surface and underground,the principle of priority selection for fans is proposed,and the anti deformation construction technique measures for fans are put forwards. Mainly aiming at the lean of fans,the mining deformation observation for fans is designed. The basic rectification and repair measures that are suitable for fans are proposed,in view of safety risk that fans might lean too much affected by mining. The research will actualize the long term safe operation of wind farms built on the mining influence area without protective coal pillar. It starts an effective technical way for building wind farms in the pressure mine,with high application value.
