瓦斯爆炸、瓦斯煤塵爆炸和煤塵爆炸(以下統稱瓦斯和煤塵爆炸)會造成大量人員傷亡和財產損失,屬於煤礦重特大事故。根據煤礦瓦斯和煤塵爆炸特徵,提出了氣體(O2,CO2,CO)濃度、溫度、聲音、震動、氣壓、風速、風向、煙霧、粉塵、紅外線、紫外線、圖像等多信息融合的煤礦瓦斯和煤塵爆炸感知報警與爆源判定方法:通過多參數變化,辨識瓦斯和煤塵爆炸;通過不同位置參數變化幅度、變化的先後時序關係和傳感器損壞情況,判定爆源。提出了傳感器、電纜和光纜防護與設置方法:傳感器應採用流線形或圓弧形外殼,傳感器外殼應採用耐高溫、防火、隔熱材料;傳感器應設置在巷道頂部中央;採煤工作面和掘進工作面應設置傳感器,傳感器應設置在距工作面10~15 m處;每一段巷道(沒有分支)中部應設置傳感器;應採用鎧裝電纜和光纜,電纜和光纜應具有阻燃、耐高溫、抗衝擊等性能;電纜和光纜應埋入巷幫和底板的夾角處;電纜和光纜也可引入壓風管,用壓風管防護。

【摘要】分析了煤礦瓦斯和煤塵爆炸特徵:空氣中O2濃度迅速降低,CO2和CO等有毒有害氣體濃度迅速升高;環境溫度迅速升高,空氣壓力迅速增大後回落;產生較強的紅外和紫外輻射;產生高溫、高壓、高速的爆炸衝擊波和火焰鋒面;產生爆炸音和震動;產生大量煙霧和粉塵;風速迅速增大後回落,風流反向;巷道垮塌、機電設備移動和損壞;造成大量人員傷亡。提出了氣體(O2,CO2,CO)濃度、溫度、聲音、震動、氣壓、風速、風向、煙霧、粉塵、紅外線、紫外線、圖像等多信息融合的煤礦瓦斯和煤塵爆炸感知報警與爆源判定方法:通過多參數變化,辨識瓦斯和煤塵爆炸;通過不同位置參數變化幅度、變化的先後時序關係和傳感器損壞情況,判定爆源。提出了傳感器防護與設置方法:傳感器應採用流線形或圓弧形外殼,傳感器外殼應採用耐高溫、防火、隔熱材料;傳感器應設置在巷道頂部中央;採煤工作面和掘進工作面應設置傳感器,傳感器應設置在距工作面10~15 m處;每一段巷道(沒有分支)中部應設置傳感器。提出了電纜和光纜防護與設置方法:應採用鎧裝電纜和光纜,電纜和光纜應具有阻燃、耐高溫、抗衝擊等性能;電纜和光纜應埋入巷幫和底板的夾角處;電纜和光纜也可引入壓風管,用壓風管防護。【Abstract】Characteristics of coal mine gas and coal dust explosion are analyzed: Concentration of O2 in air decreases rapidly, while concentrations of CO2, CO and other toxic and harmful gases increase rapidly; Ambient temperature rises rapidly, and air pressure increases rapidly and then falls; Stronger infrared and ultraviolet radiation are generated; High-temperature, high-pressure, high-speed explosion shock wave and flame front are generated; Explosion sound and vibration are generated; A large amount of smoke and dust are generated; Wind speed increases rapidly and then falls, and wind flow reverses; Roadway collapses, electromechanical equipment is moved and damaged; A large number of casualties are caused. A coal mine gas and coal dust explosion perception alarm and explosion source judgment method based on multi-information fusion of gas (O2, CO2, CO)concentration, temperature, sound, vibration, air pressure, wind speed, wind direction, smoke, dust, infrared, ultraviolet and image is proposed: Gas and coal dust explosion can be identified through change of multi-parameters; Explosion source can be determined according to change range, change sequence of the parameters and sensor damage at different positions. Protection and setting methods of sensor are proposed: Sensor should be equipped with a streamlined or arc-shaped shell, and the sensor shell should use high-temperature resistant, fireproof and heat-insulating material; Sensor should be installed in center of roadway top; Sensor should be installed on mining face and heading face, and the sensor should be located 10-15 m away from the working face; Sensor should be installed in the middle of each roadway(without branches).Protection and setting methods of cable and optical cable are proposed: Armored cable and optical cable should be adopted, and the cable and optical cable should have properties of flame retardant, high-temperature resistance and impact resistance; Cable and optical cable should be buried at the angle between roadway side wall and floor; Cable and optical cable can also be protected by introducing into compressed air duct.
