摘要:礦井通風系統(tǒng)是礦井安全生產(chǎn)的重要組成部分，是保障安全生產(chǎn)的基礎(chǔ)，礦井通風系統(tǒng)能否正常工作與礦井內(nèi)工作環(huán)境條件、生產(chǎn)效率、安全生產(chǎn)密切相關(guān)。但是，現(xiàn)在仍有大量開采多年的老礦系統(tǒng)極為復雜，礦井在日常生產(chǎn)中所遵從的分區(qū)通風格局抗災能力不足，在強烈的擾動面前有可能形成嚴重的風流紊亂，因而需要有預先的判斷和分析。因此，對礦井局部通風系統(tǒng)的合理性、可靠性和抗災能力的分析，對于提高礦井安全管理水平均有著重要的作用。 針對我國傳統(tǒng)礦井局部通風系統(tǒng)經(jīng)常造成“無計劃”停電停風的特點，對礦井局部通風系統(tǒng)進行進一步的整改，整個系統(tǒng)采用PLC控制器的自動控制，結(jié)合組態(tài)王的監(jiān)控畫面，能夠做到對局部通風系統(tǒng)的監(jiān)控，對其瓦斯?jié)舛?、溫度、風量等的監(jiān)控，以便對各種不正常狀態(tài)和故障進行實時的報警和管理，減小事故的發(fā)生，它從一定程度上降低了采掘工作面“無計劃”停電停風的次數(shù)，提高其局部通風系統(tǒng)運行的穩(wěn)定性、可靠性、節(jié)能降耗等。 關(guān)鍵詞：礦井局部通風系統(tǒng)；PLC控制；變頻；設計
Abstract:The mine ventilation system is an important part of the mine safety production, it is to ensure safety in production ,mine ventilation system can work normally or not ,which is closely related to the mine working environment condition, production efficiency, safety in production. But now, there are still a lot of old mine of mining system is extremely complex, partition ventilation pattern which mine in daily production must follow is lack of resilience, when facing the strong disturbance, it may form severe airflow disturbance, so there is need to judge and analyze ahead. Therefore there is need to analyze the rationality, reliability and resilience of local ventilation system, which plays an important role to improve coal mine safety management level. In view of characteristic that our country traditional mine local ventilation system often resulted in "no plans" to stop power and the wind, to improve pit local ventilation system, the whole system adopts the automatic control of PLC controller, combined with the configuration king of monitoring menu, able to do on local ventilation system monitoring, can do local ventilation system to monitor, the gas concentration, temperature, air flow rate surveillance and so on, so that to manage various abnormal state and fault alarm ,educe the accident, which ,to a certain extent ,reduce the frequency of mining work face" no plans" power to stop the wind, to improve stability, reliability, saving energy and reducing consumption of the local ventilation system. Key words: The mine local ventilation system ;PLC control; frequency conversion;design
