title: Assessment of rockfall potential of limestone hills in the Kinta Valley

abstract: Limestone hills are an astounding natural beauty to the landscape due to their unique features formed by the dissolution of carbonate by water (natural dissolution).However, depending on a hill's location, it may also pose danger to humansand properties due to the presence of extensive joints and fractures within the limestone hill.This study was conductedtoassess the condition of seven limestone hills in kinta valley, perak.They are gunung rapat, gunung datok, gunung lang,gunung paniang, gua kandu, gunung panjang, and gua tempurung.The significance of studying these hills are their locationsthat are close to roads, residential areas and the possible development as tourist attractions.A total of twelve assessment stations with two to three stations for each of the hills were set up to assess their stability using the rock mass strength (RMS) system.The geological conditions of the hills were assessed by seven components in the RMS system for rockfall assessment: Intact rock strength (using a Schmidt hammer), weathering, spacing of joints, joint orientations, width of joints, continuity of joints, and outflow of groundwater.Subsequently, the hills are classified into very strong, strong, moderate,weak, or very weak based on the sum of ratings for all the components.The assessment has revealed that the slopes at the assessment stations at gunung rapat and gunung lang are classified as weak whilst that at gunung datok is classified as moderate to weak.The main reasons are these hills are heavily jointed with smaller joint spacings (below 300 mm),joints daylighting steeply out of slopes (85-90°), wider joint opening (larger than 20 mm) and very low Schmidt hammer rebound values (below 35 an average).Based on these factors, these hills were classified as weak (RMS: below 50) and highly susceptible to the occurrence of rockfalls.The remaining five hills have moderate susceptibility based on the RMS. © Penerbit UMT.
