摘要

摘要: 目前针对煤量检测的研究大多侧重于煤矿井下带式输送机的煤量检测和识别，对综采（放）工作面刮板输送机的煤量检测仅停留在转载机处安装红外扫描装置，检测技术单一，且由于转载机位于刮板输送机卸煤处，红外扫描装置检测的是转载机的载煤量，不能直接反映刮板输送机上的实时载煤量，存在较大滞后性。针对上述问题，提出一种基于数组的刮板输送机运载模型及煤量计算算法。该算法将刮板输送机设定为连续装煤的载体，通过连续数组建立刮板输送机运载模型，并表征单位长度的装煤量，结合综采（放）工作面采煤机运行速度、滚筒高度、截割深度、位置及刮板输送机运行速度与装煤系数等参数，通过多参数数学建模的方法，实现对刮板输送机单位煤量的实时模拟，进而直观反映煤矿井下采煤工艺并准确计算出刮板输送机的实时载煤量。井下工业性试验结果表明，该算法连续可靠，可以精确计算出刮板输送机实时载煤量，载煤量分布接近于理想状态，具有较高的收敛性和鲁棒性。

Abstract: Currently, most research on coal quantity detection focuses on the coal quantity detection and recognition of underground belt conveyors in coal mines. The coal quantity detection of scraper conveyors in fully mechanized working (caving) faces only stays at the transfer machine, where infrared scanning devices are installed. The detection technology is single, and because the transfer machine is located at the coal unloading point of the scraper conveyor, the infrared scanning device detects the coal loading of the transfer machine and cannot directly reflect the real-time coal loading on the scraper conveyor, resulting in significant lag. In order to solve the above problems, a transportation model and coal quantity calculation algorithm of scraper conveyor based on array is proposed. This algorithm sets the scraper conveyor as a continuous coal loading carrier, establishes a scraper conveyor transportation model through a continuous array, and characterizes the coal quantity per unit length. Combining the operating speed, drum height, cutting depth and position of the shearer and the operating speed and coal loading factor of the scraper conveyor, the real-time simulation of the unit coal quantity of the scraper conveyor is realized through the method of multi-parameter mathematical modelling. It can intuitively reflect the coal mining process of the underground coal mines and accurately calculate the real-time coal quantity of the scraper conveyor. The results of underground industrial tests show that the algorithm is continuous and reliable, and can accurately calculate the real-time coal quantity on the scraper conveyor. The distribution of coal quantity is close to the ideal state, and it has high convergence and robustness.
