“…e smaller the fuel ratio, the better the combustion performance of the coal gangue. NIE Qi−hong defined the comprehensive combustion characteristic index Sn to evaluate the combustion performance of coal [25]. For the slow-burning process of coal, the burning rate is expressed approximately with Arrhenius's law, and ( 14) is its definition.…”

Coal fire disaster caused by the spontaneous combustion of coal has always been one of the serious problems that threaten the safety of coal mining. In our study, we first solved the dynamic parameters and mechanical functions of coal gangue using the Achar differential method and Coats-Redfern integral method. Then, based on the flow and heat transfer mechanism of hot rod vapor-liquid two-phase flow, combined with coal spontaneous ignition conditions, influencing factors, coal pile spontaneous combustion temperature field structure distribution, etc., the heat transfer process of the hot rod in the coal pile (coal gangue mountain) was analyzed. Results show the average activation energies of the second stage of different types of coal mine gangue. Upon comparing the characteristic parameters of coal gangue in different regions and ages, it is found that 8# coal gangue has better combustion and burn-out characteristics, and its comprehensive combustion characteristics are second only to those of the coal gangue in Datong and higher than those in Panzhihua, Pingdingshan, and Hancheng. The higher the content of volatile matter and fixed carbon in coal gangue, the lower the ash content, and the better the comprehensive combustion performance of the coal gangue. Under the condition of sufficient oxygen supply combustion, the larger the fuel ratio, the better the burnout performance of the coal gangue. The test of the influence of the hot rod on the temperature field distribution inside the coal pile shows that the maximum cooling rate of a single hot rod to the coal pile during the test period is 33.4°C, and the maximum cooling rate reaches 39.6%. The calculated heat dissipation of the 80 h hot rod is 1.0865, 2.1680, and 3.3649 MJ, respectively.

“…In some cases, how-ever, dry cutting is recommended [1,4]. In this case, the solution to the problem of reducing the temperature of the cutting tool during the cutting process can be the so-called heat pipe [5,6]. A heat pipe is a special, additional element introduced into the cutting zone.…”

This article shows the results of research on the eff ectiveness of operation of an original tool air cooling system in cutting. A case of turning EN-GJL 250 cast iron with TH10 tungsten carbide cutting inserts without protective coatings was selected for testing. The paper gives constructional details of the tested tool cooling system and discusses the principle of its operation. The research carried out has shown that this way of cooling the cutting insert causes a signifi cant decrease in temperature in all sub-areas of the cutting zone. In addition, air cooling has been proven to signifi cantly reduce cutting tool wear and slightly improve the roughness of the machined surface. The results obtained showed that the proposed method of cooling can be successfully used in the treatment of grey cast iron.In the future, it may serve as a basis for the construction of a professional cooling system for industrial applications.
