Description of mine gas:

瓦斯主要成分是甲烷(CH4)，它是無(wú)色無(wú)味無(wú)嗅可燃的氣體，爆炸條件：濃度在 5%~16%， 氧氣大于 12%，遇明火或者溫度 650℃至 750℃就引起爆炸，濃度 9.5% 爆炸威力大；當濃度大于 16% 時(shí)，燃燒不爆炸。主要由煤體或者腐爛植物產(chǎn)生，存在狀態(tài)：吸伏式和游離式。瓦斯氣在煤礦井下是煤礦工人第敵，由于地質(zhì)、環(huán)境、空氣、工作場(chǎng)所復雜等多種原因，有一定濃度瓦斯，遇到明火就會(huì )爆炸，是礦難主要原因。為了從根本上控制重特大瓦斯爆炸事故的發(fā)生，國家煤礦安全監察局提出了瓦斯治理的十二字方針，即“先抽后采，監測監控，以風(fēng)定產(chǎn)”。

The main component of gas is methane (CH4), which is a colorless, odorless, odorless, and flammable gas. Explosion conditions include a concentration of 5% to 16%, oxygen greater than 12%, and exposure to open flames or temperatures ranging from 650 ℃ to 750 ℃, causing an explosion. The concentration of 9.5% has a high explosive power; When the concentration is greater than 16%, combustion does not explode. Mainly produced by coal or decaying plants, present in two states: trapped and free. Gas is the first natural enemy of coal miners in coal mines. Due to various factors such as geology, environment, air, and complex workplaces, there is a certain concentration of gas that can explode when encountering open flames, which is the main cause of mining accidents. In order to fundamentally control the occurrence of major gas explosion accidents, the National Coal Mine Safety Supervision Bureau has proposed a twelve character policy for gas control, which is "pumping first and then mining, monitoring and monitoring, and determining production based on wind".

瓦斯資源豐富，陸上煤層氣資源量36.8萬(wàn)億立方米，與陸上常規天然氣資源量（38萬(wàn)億立方米）相當，僅次于俄羅斯和加拿大。，瓦斯資源的開(kāi)發(fā)和利用，對緩解我國能源供應緊張狀況，意義十分重大。

The gas resources are abundant, with 36.8 trillion cubic meters of onshore coalbed methane resources, which is equivalent to the conventional natural gas resources on land (38 trillion cubic meters), second only to Russia and Canada., The development and utilization of gas resources are of great significance in alleviating the tight energy supply situation in China.

瓦斯發(fā)電機機組介紹：

Introduction to Gas Generator Unit:

礦井瓦斯發(fā)電機組，是以成熟的內燃機技術(shù)為基礎，利用煤礦抽排瓦斯為燃料驅動(dòng)燃氣發(fā)動(dòng)機工作，結合煤礦瓦斯的特點(diǎn)對柴油發(fā)電機組加以改造而成的。由原來(lái)燃油改為燃燒瓦斯，發(fā)動(dòng)機驅動(dòng)發(fā)電機運轉達到由機械能轉化為電能的目的。一般瓦斯濃度在6%-25%之間的煤礦均可發(fā)電，綠環(huán)提供功率為400kw-1200kw的礦井發(fā)電機組，具體可咨詢(xún)山東綠環(huán)（15165044999 經(jīng)理）。

The mine gas generator set is based on the mature internal combustion engine technology, uses the coal mine gas drainage as the fuel to drive the gas engine to work, and combines the characteristics of coal mine gas to transform the diesel generator set. Changing from fuel to gas combustion, the engine drives the generator to operate, achieving the goal of converting mechanical energy into electrical energy. Generally, coal mines with gas concentrations ranging from 6% to 25% can generate electricity. Green Ring provides coal mine power generation units with a power range of 400kw-1200kw.
