摘　　要：为了研究特定矿井或地区的截割比能耗,利用MG900/2400-WD采煤机在陕蒙煤田某矿区的运行数据,结合设备使用的实际工况,提出了针对不同数据类型的数据清洗算法,消除数据采集过程中的误差。首先针对速度,采高,架号三种数据分别设计了速度修正算法,完成数据修正后通过可视化采煤机架号数据变化情况,选取了45组采煤机在正常截割时的数据。最后利用采煤机牵引速度左右采高及滚筒截深,计算采煤机割煤体积。利用采煤机电机电流数据,计算采煤机割煤消耗的能量,从而得出了随着牵引速度变化,截割比能耗的变化情况。结果表明这两种算法能够分别修正速度和采高数据中存在的误差,使用清洗后的数据能够计算出的截割比能耗随速度的变化规律。截割比能耗的结果为下一阶段此采煤机的推广、设计和改进提供指导数据。In order to study the specific energy consumption of cutting in a specific mine or area,using the operation data of MG900/2400-WD shearer in a mining area of Shaanxi-Mongolia Coalfield,combined with the actual working conditions of the equipment,a data cleaning algorithm for different data types is proposed to eliminate the errors in the data acquisition process.Firstly,speed correction algorithms are designed for speed,mining height and rack number.After data correction,45 groups of shearer data during normal cutting are selected by visualizing the change of shearer rack number data.Finally,the coal cutting volume of shearer is calculated by using the mining height around the hauling speed of shearer and the cutting depth of drum.Using the current data of shearer motor,the energy consumption of shearer cutting coal is calculated,and the change of cutting specific energy consumption with the change of traction speed is obtained.The results show that these two algorithms can correct the errors in the data of speed and mining height respectively,and the change rule of cutting specific energy consumption with speed can be calculated by using the cleaned data.The result of cutting specific energy consumption provides guiding data for the promotion,design and improvement of this shearer in the next stage.
