摘　　要：我国灰岩岩溶分布很广,面积大约为2×10~6km^2,约占国土面积的1/5,这些地区往往是重要的煤产地,有60%的煤矿不同程度地受到底板岩溶承压水的威胁,受水害的面积和严重程度均居世界各主要采煤国的首位。本文以屯兰矿为例,分析奥陶系上马家沟组含水层突水因素,并提出了相应的防治措施,为煤矿安全生产提供科学依据。The limestone karst in China is widely distributed, with an area of about 2 ×10~6 km^2, accounting for about 1/5 of the land area.These areas are often important coal producing areas. 60% of the coal mines are threatened by the rock dissolving and pressure water in different degrees, and the area and severity of water damage are the first of the major coal mining countries in the world. Taking the Tun Lan mine as an example, the water inrush factors of the upper Majiagou Formation in the Ordovician system are analyzed and the corresponding prevention measures are put forward to provide a scientific basis for the safety production of the coal mine.
