Study on Wear Characteristics of Coal Drain Chute for Open Pit Mine
Authors: TAO Xuewei , XIE Guoliang , GUO Mingxiang , YANG Zirun , HUANG Yue , GONG Runjie
Published: January 2025

With the advancement of social science and technology and the escalating demand for resources, the utilization rate and load of mechanical equipment in diverse industries have become increasingly prominent. Mechanical malfunctions occur frequently, especially in material transportation, causing substantial economic losses. Mechanical wear has emerged as the principal cause of mechanical equipment failure; hence, studying the wear of particles and transportation machinery is of paramount importance. This paper utilizes the discrete element method and numerical simulation approach to investigate the influence of mechanical structure alterations on the wear of discharge chutes in coal conveyor systems. The results reveal that in terms of speed, reducing the conveyor belt speed has negligible effects on the falling trajectory and distribution characteristics of the materials but reduces the frequency of contact between the materials and the chute surface, thereby diminishing the tangential force exerted by the materials on the chute. The tangential cumulative force plays a crucial role in the wear of the chute by granular particles and can effectively alleviate the wear of the chute. With respect to the inclination angle of the conveyor belt, when increasing the angle clockwise, the influence on the falling trajectory and distribution characteristics is relatively minor, and the falling speed of the materials will accelerate. Nevertheless, the wear of the chute will decrease as the inclination angle increases. When increasing the inclination angle counterclockwise, the falling trajectory and distribution characteristics are significantly affected, and the materials will tend to concentrate, and the falling speed will decelerate, resulting in a substantial reduction in chute wear. These discoveries provide theoretical underpinnings for reducing equipment wear and optimizing coal transportation equipment.
Is There a Valuation Time Bomb Embedded in Your Client’s ESOP?
Authors: Neuzil David J.
Published: January 2025

As an employee stock ownership plan (ESOP) becomes more seasoned and its most vested employees inch closer to retirement, the manner in which the ESOP manages its annual repurchase obligation can become increasingly risky to the company because the repurchase obligation may start to “snowball.” A company with a sizeable ESOP ownership percentage that redeems the shares it purchases may find the repurchase obligation increasingly onerous as the cash outlay required to fund the repurchases grows at an exponential rate. In this article I examine a hypothetical example of a steady-state, 100% ESOP-owned company, and the impact that electing to redeem the repurchased participant shares can have on risk and value as the plan matures as compared to the identical company that elected to recycle shares.

Modeling of energy gain in bifacial vertical PV fences
Authors: Azooz Aasim A. , Ali Zeyad T.
Published: January 2025

A quantitative model-based analysis was conducted to estimate the percentage output energy ratio of vertically installed bifacial PV modules in fences, cattle barriers, and roadsides compared to the output energy of two types of monofacial PV installations. The first comparison is between the output of the vertical bifacial PV fence and the output of the same fence furnished with vertically installed monofacial PV modules. The second comparison is between the output of the vertical bifacial fence and the output of south-facing monofacial PV modules installed at the optimal inclination angle for the particular latitude. The results show that bifacial fences can produce net yearly energy outputs up to 80% higher than those of monofacial PV modules. Additionally, vertical bifacial PV fences produce only a few percent lower energy compared to optimally installed monofacial PV modules. A MATLAB software program was written to calculate the gain of fences of any geometry, and it has been made freely available. Examples of gain results for a few such geometries are presented.
