Abstract
Автоматизированная система контроля и предотвращения взрыва пылеметановоздушной смеси в комплексно-механизированном забое, включающая трубопровод орошения, высоконапорный насос, низконапорный и высоконапорный трубопроводы автоматизированной системы с задвижками с электрическим приводом и электромагнитные клапаны, форсунки для распыления воды, измерительные приборы метана, оксида углерода, влажности, запыленности шахтной атмосферы и зольности пыли, скорости движения потока воздуха в начале и конце механизированного забоя и измерительных приборов содержания метана и датчика положения, установленных непосредственно на очистном комбайне, а так же измерительных приборов давления воды в трубопроводах, соединенных через модули передачи данных с линиями связи и контролером, блок управления с линиями управления задвижками и электромагнитными клапанами, отличающаяся тем, что при постоянном контроле показаний измерительных приборов, положения комбайна в забое, задвижек и электроклапанов, которые записывают в «черный ящик», непрерывно анализируют отклонение входных и выходных параметров от заданного и приближение содержания метана, пыли и ее зольности, оксида углерода в шахтной атмосфере к нижнему пределу взрываемости пылеметановоздушной смеси и вырабатывают управляющие воздействия с предворением для рассредоточенной подачи расчетного объема тонкодисперсной воды от высоконапорного насоса через высоконапорный трубопровод, электроклапаны и тонкоструйные форсунки в пространство комплексно-механизированного забоя для обеспечения точки росы в шахтной атмосфере с учетом фактической температуре, An automated system for controlling and preventing the explosion of dust-methane-air mixture in a complex-mechanized face including an irrigation pipe, a high-pressure pump, low-pressure and high-pressure pipelines of an automated system with valves with an electric drive and electromagnetic valves, nozzles for spraying water, measuring instruments for methane, carbon monoxide, humidity, the dust content of the mine atmosphere and the ash content of dust, the speed of air flow at the beginning and end of the mechanized face and measured measuring devices for methane content and a position sensor installed directly on the shearer, as well as measuring instruments for water pressure in pipelines connected via data transmission modules with communication lines and a controller, a control unit with valve control lines and electromagnetic valves, characterized in that when constant monitoring of the readings of measuring instruments, the position of the combine in the face, valves and solenoid valves, which are recorded in the "black box", continuously analyze the deviation of the input and output parameters from the given one and approximation of the methane, dust and its ash content, carbon monoxide in the mine atmosphere to the lower explosive limit of the dust-methane-air mixture and generate control actions with the prediction for the dispersed supply of the calculated volume of fine water from a high-pressure pump through a high-pressure pipeline, solenoid valves and fine-jet the space of the complex-mechanized face to ensure the dew point in the mine atmosphere, taking into account the actual temperature,
