通过数据仿真的方法，仿真理想情况下手提盘煤仪的激光测距数据、姿态数据和定位数据，然后根据实际情况确定各误差参数，并将其依次代入仿真数据中，比较理论体积和代入误差后的仿真体积，得出误差因素对体积的影响规律，并分析了各误差的产生机理，比较了各误差因素对体积影响的大小，该研究结果为手提盘煤仪中重要误差因素的抑制或补偿提供了理论依据。

By means of data simulation, the laser ranging data, attitude data and location data of portable coal inventory instruments under ideal conditions are simulated. According to the actual situation, each error parameter is determined and brought into the simulation data. By comparing the theoretical volume with the simulation volume after errors introduced, the influence laws of all kinds of error factors on volume are obtained. The producing mechanism for each error is analyzed and the influence degree of each error factor on volume is compared. The above research results provide a theoretical basis for the suppression or compensation of main error factors in the portable coal inventory instruments.
