| 摘 要： | 对济宁何岗煤矿16上、17煤水文地质条件进行补充勘探。研究认为济宁何岗煤矿井田内主要含水层有第四纪砂砾层，山西组3上、3下煤层顶底板砂岩、太原组三灰、十下灰、十三灰及奥陶纪灰岩。16上、17煤的主要水害是太原组下部灰岩水和奥灰水，16上、17煤水文地质条件属中等局部复杂类型，开采时的矿井最大涌水量为816m3／h。断层和裂隙是诱发突水的主要因素，生产中必须采取有效的安全防水措施。

| Abstract: | Supplementary exploration of hydrogeological conditions of lower series coal （upper part of No. 16 strata and No. 17 strata） have been carried out by No. 3 Exploration Brigade of Shandong Coal Geology Bureau of Hegang coal mine in Jining city. It is regarded that major aquifers of Hegang coal mine are Quaternary sandstone aquifers, roof and floor sandstone aquifers of upper and lower part of No. 3 coal strata in Shanxi formation, No. 3 limestone, lower part of No. 10 limestone, No. 13 limestone and aquifer in Ordovician limestone of Taiyuan formation. Major water damages in lower series coal （upper part of No. 16 strata and No. 17 strata） are lower part of the limestone water and the Ordovician limestone water in Taiyuan formation. Hydro-geological conditions of ower series coal （upper part of No. 16 strata and No. 17 strata） belong to medium regional complex type. Its maximum water yield in mining is 816m3/h. Faults and fractures are the major factors in causing sudden water. Thus, effective countermeasures should be carried out to prevent water in the production period. |
