- 摘要:
- 分析了急倾斜煤层开采地表移动盆地形成的原因及其破坏规律。将急倾斜煤层实际开采空间转换为滑移空间后，根据管道走向与地表移动盆地走向的关系求得了急倾斜煤层开采地表移动盆地对管道的影响范围，并使用相关公式计算了急倾斜煤层开采地表移动盆地的最大沉降量。同时，参照有关石油行业标准，对一定长度范围内的管道的最大允许沉降量进行了计算，并给出了算例。通过对急倾斜煤层开采地表移动盆地的最大沉降量与地表移动盆地影响宽度内的管道的最大沉降量进行对比，初步判断了管道的安全性
- Abstract:
- The forming reason and failure regularity of steeply inclined coalmining area subsidence trough were analyzed. After converting steeply inclined coal seams actual mining space to slip space, the impact range of steeply inclined coalmining area subsidence trough on pipeline was calculated according to the relationship of pipeline route and subsidence trough route, and the maximum settlement of steeply inclined coalmining area subsidence trough was calculated by referring to relevant formulas. The maximum allowable settlement of certain length range on pipeline was calculated by referring to relative petroleum industry standards, and the caculation example with provided. Comparing the maximum settlement of steeply inclined coalmining area subsidence trough with the maximum settlement of pipeline within subsidence trough impact width, the safety of pipeline was preliminarily judged.
