【摘要】：隨著煤礦開采強度、開采深度的增加以及機械化程度的提高,在采煤過程中產生的粉塵也越來越多,粉塵的存在嚴重威脅著井下人員的健康及礦山的安全,為了滿足安全礦山和綠色礦山建設的需求,必須對煤礦井下的粉塵加以有效的防治,綜采工作面是粉塵產生的主要源頭,必將是粉塵防治的重點之處。 煤礦井下治理粉塵的措施有很多種,本文在參考國內外多種降塵系統(tǒng)的基礎上,結合我國煤礦綜采面的現(xiàn)有狀況,提出了基于CAN總線的高壓、恒壓噴霧降塵系統(tǒng),有效的解決了傳統(tǒng)噴霧降塵系統(tǒng)霧化效果差、耗水量大、通信不便、難以降低呼吸性粉塵等的缺點。該系統(tǒng)針對綜采工作面的割煤、移架、放煤、運煤等主要產生粉塵的生產環(huán)節(jié),分別設計了具有針對性的噴霧降塵控制方法,對綜采面粉塵濃度的降低卓有成效。 本文根據(jù)高壓噴霧獨有的優(yōu)勢,設計了基于CAN總線、恒壓、高壓噴霧降塵系統(tǒng),該系統(tǒng)井下部分主要由主控制器和噴霧控制器組成,噴霧控制器主要用于采集傳感器的信號及控制球閥的開／關；主控制器主要用于數(shù)據(jù)處理、顯示、輸入?yún)?shù)及控制增壓水泵以保持管道中水壓恒定等,主控制器和噴霧控制器通過CAN總線來實現(xiàn)數(shù)據(jù)交換。地面監(jiān)控中心通過安裝于計算機里的上位機軟件與主控制進行數(shù)據(jù)的交換,實現(xiàn)地面與井下的信息交互。其中主控制器采用STM32處理器,噴霧控制器采用ATMega8處理器,CAN總線電路采用MCP2515總線控制器和TJA1050總線驅動器。該系統(tǒng)通過實驗表明：該系統(tǒng)方案設計合理,降塵效果顯著,滿足煤礦企業(yè)的需求,具有很好的市場前景和推廣價值。
[Abstract]:With the increase of mining intensity, mining depth and mechanization degree, more and more dust is produced in the process of coal mining. The existence of dust seriously threatens the health of underground personnel and the safety of mines. In order to meet the needs of the construction of safe mines and green mines, it is necessary to effectively prevent and cure the dust in coal mines. The fully mechanized coal face is the main source of dust production and will be the focus of dust prevention and control. There are many kinds of measures to control dust in coal mine. Based on the reference of various dust control systems at home and abroad and the existing situation of fully mechanized coal mining face in our country, a high pressure and constant pressure spray dust control system based on CAN bus is put forward in this paper. It effectively solves the disadvantages of the traditional spray dust control system, such as poor atomization effect, large water consumption, inconvenient communication, difficult to reduce the breathing dust and so on. Aiming at the production links of coal cutting, moving frame, coal drawing and transporting coal in fully mechanized coal face, the system has designed the corresponding spray dust control method, which is very effective in reducing dust concentration in fully mechanized coal face. According to the unique advantages of high pressure spray, this paper designs a dust control system based on CAN bus, constant pressure and high pressure spray. The downhole part of the system is mainly composed of main controller and spray controller. The spray controller is mainly used to collect the signal of the sensor and control the opening / closing of the ball valve, and the main controller is mainly used for data processing, display, input parameters and control of the booster pump to keep the water pressure in the pipeline constant, etc. The main controller and spray controller can exchange data by CAN bus. The ground monitoring center exchanges the data with the master control by the computer software installed in the computer to realize the information exchange between the ground and the underground. The main controller uses STM32 processor, the spray controller adopts ATMega8 processor and can bus circuit uses MCP2515 bus controller and TJA1050 bus driver. The experimental results show that the scheme of the system is reasonable, the dust control effect is remarkable, and the system meets the needs of coal mining enterprises. It has a good market prospect and promotion value.
