摘要

摘要: 煤矿井下同时开采多个采煤工作面，任一巷道分支风量调控变化会引起其余巷道分支风量变化，矿井内任一采煤工作面风量调控会影响该矿井其他采煤工作面风量发生改变，因此，有必要对多个采煤工作面风量进行智能调控。然而目前对采煤工作面风量智能调控的研究主要基于矿井风量自动调控算法或矿井风量调节设备，缺乏对多个采煤工作面风量按需动态联动调控系统方面的研究。针对上述问题，提出了一种多个采煤工作面风量按需动态联动调控系统设计方案。以部署在山西天地王坡煤业3308采煤工作面回风联络巷内的百叶式远程自动调节风窗为研究对象，采用计算流体动力学（CFD）数值模拟方法模拟调节风窗流场分布规律，利用Origin软件对调节风窗过风面积与风阻之间的非线性关系进行拟合，得出两者之间的函数关系，现场实测得到的调节风窗风阻与拟合计算得到的调节风窗风阻之间相对误差＜6%。根据调节风窗过风面积与风阻之间的关系函数、多个采煤工作面风阻调节量联合解算方法开发了上位机解算软件，基于上位机解算软件、井下隔爆兼本安型控制分站、百叶式远程自动调节风窗构建了多个采煤工作面风量按需动态联动调控系统。对3308采煤工作面和3203采煤工作面风量进行按需动态联动调控现场应用，表明工作面风量调控目标值与调控之后实际风量之间相对误差＜7%，说明多个采煤工作面风量按需动态联动调控系统具有一定的使用效果。

Abstract: When multiple coal working faces are mined at the same time in the coal mine, the change of branch air volume of any roadway will cause the change of branch air volume of other roadway. The air volume control of any coal working face in the mine will affect the air volume change of other coal working faces in the mine. Therefore, it is necessary to intelligently control the air volume of multiple coal working faces. However, the current research on intelligent control of air volume in coal working face is mainly based on automatic control algorithm of mine air volume or mine air volume control equipment. It lacks the research on the on demand dynamic linkage control system for air volume of multiple coal working faces. In order to solve the above problems, this paper puts forward a design scheme of on demand dynamic linkage control system for air volume of multiple coal working faces. Taking the louvered remote automatic regulating air window deployed in the return air crossheading of 3308 working face in Shanxi Tiandi Wangpo Coal Industry as the research object, the computational fluid dynamics (CFD) method is used to simulate the flow field distribution of the regulating air window. The Origin software is applied to fit the non-linear relationship between the wind area of the regulating air window and the wind resistance, and obtain the functional relationship between them. The relative error between the wind resistance of the regulating air window measured on site and that calculated by fitting is less than 6%. Based on the functional relationship between the wind area and the air resistance of the regulating air window and a joint calculation method of wind resistance regulation of multiple coal working faces, the upper computer calculation software is developed. And based on the upper computer calculation software, the underground explosion-proof and intrinsically safe control substation and the louvered remote automatic regulating air window, the on demand dynamic linkage control system for air volume of multiple coal working faces is constructed. The on demand dynamic linkage control of air volume on demand is carried out on 3308 and 3203 coal working faces in Wangpo Coal Industry. The field application shows that the relative error between the target air volume and the actual air volume after control is less than 7%. This result indicates that the on-demand dynamic linkage control system for air volume of multiple coal working faces has certain use effect.
