摘要： 在大型封闭储煤场室内自动消防炮设计中，布置在马道上的自动消防炮主要受煤堆垛及屋面遮挡影响,设计最大保护半径受到抑制，相关规范及文献缺少应对措施。以内蒙古自治区某地一座20万t储量的封闭室内储煤场为例，研究煤堆垛及屋面对自动消防炮设计的影响及其应对方法。首先，利用自动消防炮火源探测器视角及射流轨迹特点，选定自动消防炮在建筑宽度方向最佳布置区域及高度范围；其次，依据自动消防炮设计最大保护半径，确定其在建筑长度方向的最佳布置位置；然后，以0°角喷射的射流轨迹复核自动消防炮在该平面位置及高度上的实际保护范围，最终消除煤堆垛及屋面对自动消防炮的遮挡影响。

Abstract: In the design of automatic fire monitor system in large?scale closed coal storage yards, the automatic fire monitors arranged on the horse road are mainly affected by coal stacking and roof, and the design maximum protection radius is suppressed. But the relevant standards and literature lack corresponding countermeasures. Taking an example of a closed coal storage yard with 200,000 t of reserves in a certain place in Inner Mongolia, the influences of coal stacking and roof on the automatic fire monitors and countermeasures were studied. Firstly, the viewing angles of fire source detector in automatic fire monitor and jet trajectory characteristics were utilized to select the optimal layout area and height range of the automatic fire monitors in the direction of building width. Then, according to the maximum protection radius of the automatic fire monitor, determined the best position in the direction of building length. After that, the actual protective range of the automatic fire monitors was reviewed with the jet trajectory sprayed at an angle of 0°. Finally , the influences of coal stacking and roof on the automatic fire monitors were eliminated.
