He concluded that the danege to the Talons' <br />hrne was not caused by ffitI's tu~sgroumd mining of the 1st Notch Main. <br />He stated that the actual extractiozn ratio far the 1st North Main was <br />34 percent and that no subsidence would oxair because of an adequate safety <br />factar for the pillars. He explained that Gerity had azi~itrarily used an <br />extraction ratio of 90 peroE+nt in the catputer t[odel to predict subsidence <br />near the T`attms' house acrl that, as a result, his results wets psrnd'necus. <br />O!1 August 23, 1995, In separate lettets, IY'4a SnfOImed c8['1 and the <br />Tatums that it had cortQleted its investigaticm of daiege to the Tatume' <br />horse an3 had concluded that the house was not within an arcs in which mine <br />subsidence was ocauring and that, thetefore, the house was not subject to <br />mine subsidence ioopacts.
