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 $68,498Won/m^3$. 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.

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 벌목 및 조재와 타워야더에 의한 집재, 임내작업차에 의한 소운재, 트럭에 의한 운재작업으로 이루어진 임목수확작업시스템 D가 63,482원/$m^3$으로 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 및 산림바이오매스 이용을 위한 효율적인 작업시스템이라고 판단된다.
