산림바이오매스 이용을 위한 산림작업 공정 및 비용 분석(II) −작업비용 분석 − = An Analysis of the Operational Productivity and Cost for the Utilization of Forest-biomass(II) − the Analysis of Operational Cost −

다국어 초록 (Multilingual Abstract)

This study was analyzed the operational cost of logging and chipping operations in order to develop the efficient logging operation system for the utilization of forest-biomass. Analysis of the operational cost of logging operation systems, the operation system D which include chain saw, tower-yarder, mini-forwarder and truck was calculated the lowest cost to be 68,498 Won/m3. In the utilization of forest-biomass, the operation system E which include chipping by mini-chipper at the site, forwarding of chips by mini-forwarder, transportation of chips by truck was estimated to be 90,770 Won/Ton. Thus, These results are determined as an effective operating system for logging operation and the utilization of forest-biomass.

국문 초록 (Abstract)

현재 우리나라의 주요 임업기계에 의한 임목수확작업시스템에서 벌목 및 조재, 집재, 소운재, 파쇄 등의 목재생산 및 파쇄작업에 대한 작업비용을 분석하여, 산림바이오매스 이용을 위한 효율적인 임목수확작업시스템을 구축하기 위한 기초자료를 제공하고자 수행하였다. 임목수확작업시스템의 작업비용을 분석한 결과, 체인톱에 의한 벌목및 조재와 타워야더에 의한 집재, 임내작업차에 의한 소운재, 트럭에 의한 운재작업으로 이루어진 임목수확작업시스템 D가 63,482원/m3으로 가장 적은 비용이 소요되는 것으로 나타났다. 또한, 산림바이오매스 이용을 위한 작업시스템의 작업비용을 분석한 결과, 소형 목재파쇄기에 의한 현장파쇄, 임내작업차에 의한 칩 소운반, 트럭에 의한 칩 운반작업의 작업시스템 E가 90,770원/ton으로 가장 적은 비용이 산출되었다. 따라서, 이들의 결과가 임목수확작업 및산림바이오매스 이용을 위한 효율적인 작업시스템이라고 판단된다.
