Abstract

Nowadays, a roadheader as a mechanical excavator is in high demand, especially for mines under various conditions and tunnels where TBMs are inapplicable. However, the records of roadheaders in Korea are seldom reported. Moreover, the number of countries with their intrinsic design and manufacturing technologies of roadheaders is very limited. Therefore, this study aimed to analyse the excavation principles of roadheader as well as its key design parameters for its optimized selection and design. In addition, the database with 143 world-widely collected roadheader design data was built, and a few statistical correlations were derived from it. A schematic procedure for roadheader design based on the database was also proposed.

TBM을 적용하기 어려운 터널과 다양한 조건의 광산에서 기계 굴착장비인 로드헤더의 수요가 증가하고 있다. 하지만 우리나라에서 로드헤더의 적용 실적은 거의 전무하며, 일부 국가에서만 로드헤더의 설계 제작기술을 보유하고 있다. 따라서 본 연구에서는 로드헤더의 최적 선정과 설계를 위한 로드헤더의 굴착 원리 및 핵심설계항목들을 분석하였다. 또한 전 세계 143개의 로드헤더 설계 정보들을 데이터베이스화하고 로드헤더의 설계에 활용하기 위한 통계적인 상관관계들을 도출하였다. 마지막으로 데이터베이스에 기반하여 로드헤더를 설계하기 위한 절차를 제시하였다.
