3、要任务，显得越来越重要。依照煤矿安全规程规定，进行了本次山西*集团蒲县*煤矿矿井通风阻力测定。第一部分 测定前期准备工作1.1 通风系统简介及系统图、网络图*煤矿矿井通风方式为中央并列式。通风方法为机械抽出式。全矿现有两个进风井：主斜井和新副斜井，一个回风井：新回风立井。矿井由两台对旋式轴流通风机担负矿井供风任务，其中一台备用，两台主扇型号均为FBCDZ-8-21型，阻力测定期间，2#风机运行。*煤矿现布置有两个准备工作面，分别是2101准备工作面和2201准备工作面，布置两个掘进工作面，分别为副水仓掘进工作面和采区皮带巷掘进。图1为*煤矿通风系统及阻测测点布置图。图2为*煤矿通风网络图。1.

4、2 测定方法及仪器本次矿井通风阻力测定的风压测量选择气压计法中的逐点测量法。测定应用2台JFY型数字式压力测定仪，测定前对此2台压力测定仪进行了5小时对比校正，满5小时后，各仪器相对误差不大于1mmH2O，符合测定精度要求。其它测量仪器为风表、计时器、卷尺等。在测定中，井上组与井下组同时测定。基点选择在工业广场新副斜井井口。首先测定基点绝对压力，然后，井上组测定基点气压相对变化。井下组测定测点的相对压力、风速、断面、温度。测定绝对压力的单位为百帕，测定精度为0.1百帕，相对压力测定单位为mmH2O，测定精度为0.1mmH2O。图1 *煤矿通风系统及阻测测点布置图图2 *煤矿矿井通风网络图1.3

5、 阻力测定测点及阻测路线布置本次测定，全矿共布置46个主要压力测点，测定风路67条。为了提高测定精度，测定过程中，井下布置了一定数量的辅助测点。阻测路线一条：新副斜井-31采区轨道大巷-2101工作面-2101轨道回风巷-二采区集中回风巷-回风联络巷-31采区回风大巷-总回风大巷-新回风立井-风硐详见矿井通风系统与阻测测点布置图、网络图（图1、图2）。1.4 测定前期数据的收集、填图与表格准备测定前期收集整理的资料与数据主要包括：测点位置、测点编号、测点标高、巷道编号、巷道名称、巷道支护与断面形状、巷道长度及风机参数等。这些参数在井下测定前分别填写了表格与图纸。第二部分 测定原始数据记录 2.
