煤礦坑道之調查方法及其案例

Survey on Abandoned Coal Mine Adits

摘要


台灣北部山麓地區早年盛產煤,其採煤活動主要發生於坡地且為地下開採,因此在產煤地區坡地下存在許多坑道。隨著煤礦陸續停採,而坡地開發日益興盛,煤坑問題遂形成今日坡地開發之潛在災害原因之一。本文即希望藉由台灣煤層特性及台煤以往採煤活動之簡單介紹,讓大家對於台煤開採之基本資料有所了解,並由簡單之主要煤坑調查方法說明二則煤坑調查案例,提供未來煤坑調查時之參考。

The northern coastal area of Taiwan was prosperous for coal mining during the early stage of development of Taiwan near the turn of the century. Underground coal mining was mainly concentrated in the foothills, and the numerous coal mine adits were left since the coal mining industry gradually exhausted. Following the economic growth and the soaring of slope-land development, the coal mine adits have become a potential hazards for suburban hillside development.The purpose of this paper is to illustrate the characteristics of coal formations and the coal mining history in Taiwan. The method of survey on the main coal mine adits and two examples of survey on the abandoned coal mine adits are also presented in this paper.
