江西煤炭科技2023年第1期摘要：西山矿区普遍缺少主采煤层顶板“两带”实测数据，仅套用《煤矿安全规程》中的经验公式作为防治水评价及设计计算的依据，与实际情况存在较大偏差，数据不可靠。为形成本区实用性强的煤层顶板“两带”计算的经验公式，通过收集矿区多个矿井相关资料，得到其冒落带、导水裂隙带的理论计算值和实测值，应用MATLAB软件对实测值分析得到冒落带、导水裂隙带高度的回归方程，以马兰矿18301工作面为例，给出其理论计算公式，设计井下仰孔压水试验探测方案。采用该方程计算可使冒落带精度提高3.26m，导水裂隙带高度的精度提高3.80m，对西山矿区各矿井有效预测、防治顶板水害隐患具有重要意义。关键词：回采工作面；冒落带；裂隙带；压水试验法；回归方程中图分类号：TD325+.3文献标识码：B文章编号：1006-2572（2023）01-0096-04ResearchandAnalysisof“TwoZones”at18301WorkingFaceinMalanCollieryZhaoXiaohui（MalanColliery,XishanCoalPowerGroup,Gujiao,Shanxi030200）Abstract:Duetotheunreliabledataobtainedfromtheempiricalformulaintheexistingregulations,Xishanminingareagenerallylacksthemeasureddataofthe"twozones"oftheroofofthemaincoalseam,inordertoformanempiricalformulaforthecalculationofthe"twozones"ofthecoalseamroofwithstrongpracticabilityinthisarea,thepaperobtainsthetheoreticalcalculationvaluesandmeasuredvaluesofthecavingzoneandwaterconductingfracturezonebycollectingtherelevantdataofseveralminesintheminingarea,obtainstheregressionequationoftheheightofthecavingzoneandthewaterflowingfracturezonebyanalyzingthemeasuredvalueswithMATLABsoftware,anddesignstheundergroundwaterpressuretestdetectionschemefor18301workingfaceofMalanColliery,whichcanimprovetheaccuracyofthecavingzoneby3.26mandtheaccuracyoftheheightofthewaterflowingfracturezoneby3.80m,andisofgreatsignificancefortheeffectivepredictionandpreventionofthehiddendangerofroofwaterhazardsintheminesofXishanminingarea.Keywords:workingface;cavingzone;fissurezone;pressurizedwatertestmethod;regressionequation马兰矿18301工作面“两带”研究分析赵潇辉（山西焦煤西山煤电马兰矿，山西古交030200）西山煤电集团所属矿井均面临近距离煤层探放水问题，层间距59.36～82.47m，由于探放水不彻...
