Q: Coal roadway, rock roadway and semi coal rock roadway is how to divide: Coal roadway, rock roadway and semi coal rock roadway:First, the coal lane: if the roadway section, the coal seam accounted for more than 4/5, known as the coal lane; specifically for coal mining and excavation of the roadway.

Q: How many tons of coal can be produced by 1 tons of coal? What is the proportion of them in general?: The amount of ash in the coal depends on the ash content of the coal. General coal ash from 10% to about 40% or even higher

Q: The basic situation of coal occurrence in coal mining area: (2) the occurrence characteristics of coal in the corner coal, the complex condition of the corner coal, the main features are as follows: 1The irregularity of the shape of a block with irregular shapes such as triangle, trapezoid, leaf shape, etc.It is decided that the existing large scale fully mechanized coal mining equipment is not adaptive; the two is the instability of coal thickness changeQualitatively, that is, by the influence of the geological factors, such as fault, erosion zone and so onThe adoption of the existing E art equipment is unreasonable; three is the complexity of mining conditions,That is to say, the surrounding area is affected by the mined out area or fault structural beltFragmentation, water, fire, gas and other natural disasters threatening, from a security point of view need to increase technologyManagement measures

Q: Activated carbon rain has been poured into the useful: Activated carbon in our life is mainly used to absorb harmful gases and substances, especially in the home decoration used more. Shijiazhuang in addition to formaldehyde fixed enterprise better than good Shijiazhuang Environmental Protection Engineering Co. Ltd. senior engineer Zhang Gong said: the market there are many brands of activated carbon, but the quality is uneven, there are a lot of ordinary carbon as active carbon. So, how to identify and select activated carbon?.

Q: Why is heating charcoal poisoning??: Fire, to prevent carbon monoxide poisoning, every night before going to sleep should confirm the heating coal or charcoal is burned, or water extinguish fire. The fire should keep the environment ventilation brazier shall be sealed with the fire, to install the chimney. Gas equipment should not be placed in a living room or poor ventilation, with a gas water heater bath, but also to maintain ventilation, bath time should not be too long. An air-conditioned car can also produce carbon monoxide, so it's impossible to sleep in a closed car

Q: How much is a cubic meter of natural gas?: Oil and natural gas 1.3300 fand kcal/mNatural gas field 1.2143 fand kcal/mPower 0.1229 kgce/ (kw.h)

Q: I use a activated carbon respirator (Miguel card please see picture), but the product did not specify how long you can use, only that can smell the poisonous gas is to be replaced, but the smell is not good, for fear of insecurity, would like to ask if there is a smell of paint in this environment. How long you can use mask is safe, by the hour: Do not use in the oil gas environment (the above products apply to rubber, fur manufacturing, battery, chemical, mining, petroleum, nuclear engineering, shipbuilding, crafts, crystal, papermaking, brewing, agriculture, petrochemical, environmental sanitation, glass manufacturing and other industries).

Q: What is the role of ordinary charcoalCharcoal residue of jujube wood: Agricultural fieldTo improve the ground temperature: the soil after the application of carbon powder, as the black carbon particles absorb solar heat, soil temperature can increase a few degrees Celsius, promote seed germination, in particular, can promote the germination of seeds not easy to germinate, improve germination rateSoil improvement: applying carbon powder in the soil, can generate root grain bacteria on the carbon surface, thus forming the agricultural soil for plant cultivation, the so-called "continuous cropping obstacle". And the carbon on the grains, beans and vegetables grow, color and taste.Keep moisture, carbon in the relative humidity is 50%, can quickly absorb about 20% of the water, can be used to maintain soil moisture. It also can improve the permeability of soil and water, to provide a good living space for the benefit of plant microbe.

Q: Filtration of activated carbon can be used repeatedly?: Of course, but the effect of repeated use and time is greatly reduced. Because the activated carbon adsorption of other substances, it is difficult to remove the general method

Q: White melon seeds produced by the mechanism of carbon why taste: Mechanism charcoal is made of sawdust, wood residue, peanut shell and straw. Because of easy combustion, high thermal efficiency, long combustion time, is currently the most commonly used barbecue carbon. However, due to the processing in order to shape, often before the addition of binder, the combustion will produce harmful gases
