摘要
为了获得较为准确的底板破坏深度预测公式,基于多元回归分析法,结合大量实际资料对底板抗破坏能力、采厚、工作面斜长、采深、岩层倾角这5个与底板破坏深度有直接影响的因子进行线性回归分析,通过比较获得精确度较高的预测公式。通过对古汉山矿底板破坏深度预测实践,表明预测公式具有很强的实用性。
In order to obtain the accurate forecast formula of floor destroying depth, on the basis of multiple regression analysis methods, combining large amount reality data, the article carries out linear regression analysis on floor anti-damage ability, mining thickness, working face inclined length, mining depth, rock stratum angle which have directly effect on floor destroying depth.Through comparison, the article gets the forecast formula with high accuracy. Practice shows that forecast formula has strong practicability.
