Fire extinction by means of furnace smoke is a new technique for fighting mine fires. This article was written on the bases of results obtained from field experiments and researches made during the years of 1960 to 1964. It consists of five main secti-ons, namely, Preparation of Furnace Smoke, Infuson of Furnace Smoke, Control of Air-leakage in Fire Area, Effects of Fire Extinction by Furnace Smoke and Action of Furnace Smoke in Fire Area.A description is made of the preparation of furnace smoke, infusion methods, as well as the experince of controlling air-leaking in fire area.The fire-extinction effects of furnace smoke are discussed and summarized accor-ding to statistis and investigations based on field experimental conditions, and the va-rious influencing factors are analyzed. A brief explanation is also made of the principle of action on fire extinction by furnace smoke.Finally, the article concludes with a summary discussion on the advantages,operating conditions and outstanding questions of this fire-fighting method.

炉烟灭火是一项消灭煤矿井下火灾的新技术.本文系根据1960~1964年间现场试验和研究所得结果而写出.全文包括:炉烟的制备,炉烟的灌注,火区漏风的管理,炉烟灭火效果和炉烟在火区内的作用等五个主要部分.介绍了炉烟的制备与灌注方法以及火区漏风的管理经验.根据现场试验情况的统计和考察,对炉烟灭火的效果作了总结与探讨,对影响灭火效果的诸因素进行了分析,并且简要的阐述了炉烟灭火的作用原理.最后,对炉烟灭火的优点、使用条件、存在问题也作了扼要的论述.

Xiangdong (Eastern Hunan) Tungsten Mine is located in the east of Hunan Province. Its concentrator, put on stream early in 1956 and originally designed to process 250 tons of ore per day, has reached now the throughput over 1000 tpd since the second expansion. The deposit in this area belongs in medium-high temperature hydrothermal deposits with fissure-filling of wolframite-quartz veins. The main ore minerals are wolframite, chalcopyrite, scheelite, cassiterite and others, wolframite accounting for 75-80% of...

Xiangdong (Eastern Hunan) Tungsten Mine is located in the east of Hunan Province. Its concentrator, put on stream early in 1956 and originally designed to process 250 tons of ore per day, has reached now the throughput over 1000 tpd since the second expansion. The deposit in this area belongs in medium-high temperature hydrothermal deposits with fissure-filling of wolframite-quartz veins. The main ore minerals are wolframite, chalcopyrite, scheelite, cassiterite and others, wolframite accounting for 75-80% of total tungsten minerals. The principal gangue mineral is quartz, granite being the host rock. The concentrator flowsheet is composed of four sections, crushing and preconcentration, gravity concentration, slime treatment, and cleaning. The crushing-preconcentration section is provided with two stage crushing in closed circuit, followed by hand sorting and heavy medium separation, the latter is capable of rejeting worthless gangue amounting to 20-50% of the run-of-mine ore. In the gravity concentration section the ore undergoes two stage grinding, three stage jigging and five stage tabling. Jigging is intensified to recover 58% tungsten of total metal content in the ore. The slime treatment section recovers copper minerals by flotation, and both tungsten and tin minerals by spring tables, obtaining copper concentrate, containing 15% Cu with recovery 70%, and tungsten concentrate, assaying 53% WO_3 with recovery 45-50%. In the cleaning section table-flotation and flotation are used to separate sulphides and yield rough concentrates, magnetic separation is used to separate wolframite from cassiterite, scbeelite and other minerals, flotation—to separate scheelite from cassiterite, and hydrometallurgical process—to treat refractory tungsten middlings for production of tungsten trioxide. The Xiangdong concentrator yields fire products: wolframite, scheelite, copper and tin concentrates and tungsten trioxide. The recoveries of WO_3, Cu and Sn are 85%, 72.95% and 30% respectively.

Using the principle of fluid mechanics and heal-transfer, a mathematical description is given to the high temperature smoke-flow along the boundary layer of roadway due to mine fire. Thereafter, the paper has derived a formula for the calculation of the overall heat-transfer coefficient between the smoke-flow and the roadway wall. A new formula for evaluating the ventilating pressure caused by mine fire is also established by the author.Meanwhile the physical meaning of parameters γ and T in the world-known for-mula h = Hγ△T/T is briefly verified and discussed.The main parameters affecting ventilating pressure caused by mine fire were analysed with computer. The calculating results obtained from the newformula are compared graphically with that of the other four known formulas.

本文应用流体力学和传热学的理论,对矿井火灾时期产生的高温烟流在巷道边界层中的流动作了数学描述,在此基础上给出了烟流与巷道壁之间的复合换热系数的计算公式。笔者提出了新的火风压计算公式,并对国内外已有的公式h=Hγ(ΔJ)/T中的γ和T两参数的物理意义进行了粗略的验证。最后借助于数字电子计算机分析了主要参数对火风压的影响,并对五个算式计算的结果用曲线图进行了比较。
