100年前,菁桐与十分地区是台湾著名的煤碳产地。调查发现,菁桐矿区将煤矸石堆砌成一座座小山丘,形成“舍石山”时结构稳固;而十分矿区在邻近矿场的河畔随意弃渣形成的“舍石堆”则容易产生崩塌现象。深究其原因,可能与当时台阳矿业公司在菁桐地区的采矿运作,多半与缜密的舍石规划与决策有关;相反地,十分地区则由于部分小型采矿企业的任意舍石模式,而不时造成些微的崩塌灾害。由此可知,安全的弃废模式,可能使昔日矿区的舍石山成为当地政府机构规划为居民休闲游憩的地点。
100 years ago, Jingtong and its ten districts are well-known coal-producing areas in Taiwan. The survey found that the Jingtong mining area piled coal gangue into a small hill, forming a stable structure when it formed a “Shek Sanshan”. However, it was easy for a very mining area to form a “stone heap” in the vicinity of the mine near the mine site Produce collapse phenomenon. The reason for this may be related to the fact that the Taiyang Mining Company’s mining operation in the Jingtong area at that time was mostly related to the careful planning and decision-making of stone-cutting. On the contrary, in some areas, due to arbitrary stoneworking mode in some small-scale mining enterprises, Slight collapse of the disaster. From this we can see that the safe waste disposal model may make the former mining area of Sheksan become the planning of local government agencies for leisure and recreation of residents.
