灰色模型在矿山沉陷中的应用

Application of Grey Theory Model in Monitoring Mine Deformation

目前煤炭仍然是最主要的消耗性能源,为世界经济的发展提供动力。由于我国东部浅部煤层的枯竭以及深部煤层开采技术的不成熟,国内外学者将目光放在了“三下”压煤以及薄煤层上,这将是将来煤炭发展的主要目标之一。煤炭的地下开采会对地面造成不同程度的损害,为解决我国建筑物下压煤问题,评估因建筑物下采煤对地表所造成的损害,研究建筑物下采煤的地表移动规律是非常有必要的。通常会沿工作面主断面的走向和倾向安插观测站,但是受地表建筑物的影响,会使部分观测站缺失或没法安插。为了有效预计这种情况下的地表沉陷变形,本文提出将灰色理论模型应用于矿山沉陷监测,并通过后验差方法和关联度分析法两种方式的查验精度,最后联系工程实例验证可行性。相关研究可为矿山沉陷给予理论支撑。

Coal is still the most important consumption energy in today's society,which provides impetus for the development of the world economy.With the exhaustion of shallow coal seam in the east of China and the immaturity of deep seam mining technology,scholars at home and abroad put their eyes on"three under"coal pressure and thin coal layer.This will be one of the main goals of coal development in the future.The underground mining of coal will cause different degree of damage to the ground.In order to solve the problem of coal pressure under buildings in our country and evaluate the damage caused by coal mining under the building,it is very necessary to study the law of surface movement of coal mining under buildings.Usually,the direction and inclination of main section of working face are placed in observation stations.However,the influence of surface buildings will cause some stations to be missing or unable to be inserted.In order to effectively predict the surface subsidence and deformation under this condition,the application of grey theory model in mine is put forward,and the accuracy is checked by two ways of posterior difference method and correlation degree analysis method.Finally,the feasibility is verified by connecting with the engineering example.The related research can give theoretical support to the mine.
