Prevention of heat illness in mines MINES07

Where humidity is relatively high, the hazard is increased. More heat strain is placed on a person as the Wet Bulb (WB) and Dry Bulb (DB) temperatures get closer. The absolute values of the temperatures are of less importance than the difference between them, as it is the relative humidity that causes the problem by inhibiting body cooling by the evaporation of sweat. For example, 28 oC WB/45

Hot environment - estimation of thermal comfort in deep

2000, that would result in dry bulb temperatures exceeding 30ºC and humidity of 95% to in working faces (He, 2009). However, in Australian coal mines increasing strata temperatures at relatively shallow depths in combination with high surface ambient temperatures, e.g., in Queensland,

Effects of moisture on strata control in coal mines

01.11.1981· Controlling the l~umidity changes implies that the surface air being circulated through the mine is conditioned to reflect temperature and humidity equilibrium conditions in the mine. This may be achieved by: (1) tempering chambers, (2) air conditioning, and (3) continuous wetting. Tempering chambers. These basically consist of old worked-out areas to condition the surface air before

Effect of temperature and humidity on salt

The temperature and humidity of intake air changes the temperature and humidity of rock salt mine. The general trend of climate of Jhelum was analyzed to see the general characteristics of meteorological parameters of the region. Hot and humid summers, dry and mild winters, average annual precipitation above 900mm are associated with the climate of Jhelum. In Khewra Salt mines, the rock salt

In-mine experimental investigation of temperature rise and

the air temperature and relative humidity inside the RA, the heat flux through the tent's surfaces, the air temperature in the mine, the mine strata temperatures versus depth, and the airflow inside and outside the chamber. RadTherm heat transfer analysis software was used to develop a thermal simulation model of the RA as it was tested in the mine, using the test results as the benchmark

Control of heat and humidity in German mines

@article{osti_20020977, title = {Control of heat and humidity in German mines}, author = {Schlotte, W}, abstractNote = {In order to increase the economic efficiency of West European hard coal, great efforts are being made at present in the coal-producing countries to lower production costs. This aim is to be achieved in Germany, among other things, by a drastic increase in the saleable output

What is the average temperature in an

The average mine temperature varies considerably from pit to pit; temperature is dependent on depth of workings and how effective ventilation is. Temperatures at the coal face can be between 13

Relative humidity - Wikipedia

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor results in higher relative humidity

Heat Treatment and Ventilation Optimization in a

The low-temperature mine water stored in the middle section of the mine at 640 m depth was used as the cooling source, and a cooling system was established near the 440 m deep middle return well to alleviate the high-temperature and high-humidity conditions of the 280 m deep middle-western area. The results show that the effective air volume in the west wing at 280 m was 3.0 m 3 /s, the

locations to measure temperature and relative humidity in underground coal mines. Temperature and humidity measurements are required at all monthly survey points, statutory locations and all ventilation stations. Locations such as, entries to exhaust shafts, intake and exhaust ducts, all district regulators, longwall face areas (maingate, middleandtailgate),developmentfaceandreturn

A Method to Protect Mine Workers in Hot and

01.06.2018· In underground mines, there are many heat sources that cause the increase of temperature and humidity of air during its travel through mine airways and production workings. The mines' intake air temperature gradually increases as a function of depth, the level of mechanization, and the length the air travels through the underground openings. One of the main sources of heat in underground mines

Newport has released the iBTHX transmitter that allows users to monitor and record barometric pressure, temperature, relative humidity and dew point over an Ethernet network or the Internet

Underground Mine Ventilation

In many mines, especially in open stopes, there is sufficient air circulation to remove smoke, gases, and possibly the most dangerous dust from working faces, but the velocity is less than 25 ft. per min., hence not sufficient to afford relief to perspiring workers if the temperature and humidity are high. To meet this situation, a compressed
